Are there any plans to make this service anonymous?

e.g; Being able to route BitCoin through Tor.

There will be a proxy setting in version 0.2 so you can connect through TOR.  I've done a careful scrub to make sure it doesn't use DNS or do anything that would leak your IP while in proxy mode.

Someone correct me people, but I thought it IS already anonymous! Can the person I'm transferring money to know my IP or something?

When you send to a bitcoin address, you don't connect to the recipient.  You send the transaction to the network the same way you relay transactions.  There's no distinction between a transaction you originated and one you received from another node that you're relaying in a broadcast.  With a very small network though, someone might still figure it out by process of elimination.  It'll be better when the network is larger.

If you send by IP, the recipient sees you because you connect to their IP.  You could use TOR to mask that.

You could use TOR if you don't want anyone to know you're even using Bitcoin.

Bitcoin is still very new and has not been independently analysed.  If you're serious about privacy, TOR is an advisable precaution.

Tor is a extra layer of privacy and anonimity, but it isn't the ultimate answer. Check out http://www.torproject.org/download.html.en#Warning, to understand what Tor does and doesn't do for you.

Tor can be dangerous, like exit nodes that log information like passwords and the like.
So a major question about the security of Bitcoin when using it with Tor (or any other proxy service) arises:

• So what exactly does Bitcoin send when it connects to an IP?
• Is everything encrypted that we send over the line?
• Can someone 'steal' bitcoins by listening at the end of a proxy (or in Tor's case an "exit node")?

Speaking of security, we might just want to add a simple version checking procedure in bitcoin that will alert a user if s/he is running an "insecure version of bitcoin".

True, sending by IP through Tor trades one problem for another.  The Tor exit node can see the text of your message and potentially MITM you.

Best to only send to bitcoin addresses then.  Payments by bitcoin address are broadcast over the network as part of the normal network traffic.  All communications with the network are broadcasts of public information.

Has this TOR proxy setting been preserved in the latest versions ?

Yes tor is used,

Ive been able to use some private VPN's to get  blistering download speeds, not sure what filters i was avoiding though they ended up being applied to my traffic eventually slowing it back down,

thses filters no doubt will hit every single packet I imagine and filter it when it traverses inter country nodes, but id say small nodes would be filtered too,

while people are accessing restricted content past firewalls ie China no doubt special filters would be still catching their traffic through nodes.
