Nice to see some ambition.
I’ll leave feedback on some ventures.
Bitcoin Futures and Options Exchange
No clue on the current situation.
Already done, see http://www.bitlotto.com/
Be sure to check https://en.bitcoin.it/wiki/Trade#Gambling_sites
. I think there’s great potential here for a nice real gambling application though.
Bitcoin Escrow and Arbitration Service
and it’s in good (Gavin’s) hands.
Bitcoin Stock Exchange
Will be released soon by Nefario.
Bitcoin iPhone App
Absolutely, whether that be a wallet or just a Bitcoin based game. Search the forums for already existing attemps though, I think I saw something recently. It’d be better to join up instead of having two projects imo.
KickStarter for Bitcoin
I think the stock market would suffice for the current needs.
Bitcoin Bank and/or Credit Union
That is pretty huge, but if you can do it, go for it. Bank would be essentially an ewallet, right? Make sure to check mybitcoin.com in this case.
Bitcoin Credit Ratings
, but integration with social networks would definitely be nice.
Bitcoin Bond Market
Good idea, there’s certainly demand for an automated solution at the moment, although I think that will be covered by the upcoming stock market, too.
Bitcoin Shopping Cart and Business Solutions
This is needed the most in my opinion. Merchants are still having trouble setting Bitcoin up.
