Just looked into this myself.  CampBX accepts USPS money orders, personal checks, and payments from bank bill-pay services.

Be very wary of anyone offering weekly dividends.  It could easily be a Ponzi scheme.

That said, there are some businesses paying dividends on the GBLSE: https://glbse.com/assets 

I'd still do my research though.

Sounds nice.  Mine was not optimized at all. 

I'm curious to see the code.  Mostly wondering how you solved the problem I was encountering, updating the UI from native threads.

If you want to explore further, I can recommend this collection of essays: http://www.amazon.co.uk/The-Matrix-Philosophy-Welcome-Popular/dp/081269502X/  Before reading, note that it was published prior to any of the sequels.

I pledge to spend at least $250/year at Newegg in Bitcoin.

I wanted to report that it seems to be working great so far.

Thanks Josh.

I'm already switching my clients to Dreamhost from GoDaddy in protest of SOPA.  I'm glad to discover the cofounder also supports Bitcoin.

Also I like the concept of this service.  Before trusting the site with an API key though, is there any way the community could verify Josh's identity?  Please understand the healthy need for suspicion.

Ogrr could wind up serving as a niche market to introduce Korea to Bitcoin.  We're all aware of the extent to which Koreans love Blizzard games. Reports are that that the new real-money auction house feature of Diablo III will not be available in Korea, due to concerns that it resembles gambling. This will encourage players to continue privately trading virtual items.  The Korean-language subforum (한국어) already shows significantly more activity than any other language subforum: https://ogrr.com/forum.php?f=45

To mine with your GPU in OSX, try this version of Diablo Miner:

Also, Lion has the best OpenCL performance.

I would think so, as long as it as an ARM CPU.  And you can manually configure the number of threads to take advantage of multiple cores.

I ported cpuminer to Android over the weekend, mostly as an exercise for learning Android development. 

I haven't fully worked out a UI solution.  Currently you can only view the status output through the debug console.  Having issues with Java callbacks from a native environment.

Perhaps when I get it a bit more polished I'll share if anyone is interested.

Of course it would be impractical to actually mine with it.  Although you never know, perhaps one day someone in some remote village with a solar powered phone, will download an app and run it for an hour or so to earn a few satoshis with which to play.  I'd like to integrate p2ppool and a wallet to make it an easy one-click solution.  Also sooner or later Android is bound to support openCL.

Devices other than smartphones (not tied to a service account) will have NFC chipsets as well.  Also second-hand marketplaces exist for purchasing phones without service contracts.

I've seen suggested a few times that stores offer customers promotional rebates of bitbill (or some other form of a physical private key).

From the perspective of a merchant, the likely return on investment seems small.  Many customers would simply disregard and promptly dispose of their bitbills.

So I suggest printing a bitbill with an expiration date.  The merchant would retain the private key.  After a period of time, if the coins have not been spent, they could be reclaimed by the merchant.  The financial cost of the promotion should be greatly reduced.

I think Reg is referring to the comment thread of this blog entry:

Encrypting the private key with a PIN wouldn't solve it since the merchant would still see the decrypted key. That would prevent middlemen from picking up the card and emptying the balance though.  

Merchants storing credit card numbers is very different than storing private keys.  Firstly merchants are reluctant to attempt anything fishy with credit card numbers because they have to answer to the payment processor, who could cancel their merchant account.  

To allow merchants to "pull" funds properly would seem to need a similar banking infrastructure to what is in place now. Banks or credit card companies would simply denominate and store funds in BTC instead of USD.  Fees would of course still be involved to facilitate to banks as intermediaries.

The alternative, if users are to control their own funds, is to have the user "push" the transaction, likely with the use of a smartphone as you describe.  You are right, this can be a clumsy process, scanning QR codes.  There is room for improvement and perhaps NFC adoption will help smooth the process.  
Right, the loss would be reduced.  It's just something that consumers would need to fully understand.

In this situation a customer would be sharing their private key with everyone that handles the card.  An unscrupulous merchant or employee could then transfer funds from that account whenever desired.  And since transaction are non-reversable the consumer would have no recourse, no 1-800 number to call to have the funds reinstated. 

That is how you loose the average person to the concept of bitcoin, by telling them that all they need to know is that it functions identically to a concept with which they are already familiar, such as a credit card.  Then reality strikes and the consumer is forced to discover the nuances that they couldn't be troubled to learn in the first place.

Thanks to the devs of P2Pool for making a fine product and to Broken and Eleuthria for answering my questions.

Thank you.  So with a GPU hashing at 400MH/s should I expect to see a share per ~0.6hr?  I assume one share in this pool is not equivalent to a share in another pool such as Eligius, correct?  I should still expect a similar payout over time though, even though the rate of shares is not the same?
