I don't think so, no... I mean it's possible that feature is written into the bitcoin-qt client, but I doubt it. There is support for broadcasting raw transactions, but that really isn't something you want to do -- I mean it would take longer to figure out how to do it that way than to just wait for the client to catch up with the blockchain.If you just simply can't wait -- although I'd recommend that you do anyway -- what you can do is go into the bitcoin-qt client (I'm assuming that's the one you're using), go to the "help" menu, and click on "Debug Window". Then in there, click on the "Console" tab. Then in the little entry box, what you want to do is type "dumpprivkey BITCOINADDRESSHERE" (obviously replace the caps with the address you sent the coins to).Then find the option to import a key or wallet or whatever into blockchain, and you can then send them from blockchain. You may have to unlock your wallet before dumpprivkey will work (you definitely will have to if you keep your wallet encrypted, which you should). To get a list of all supported commands, you can type "help." Note that this is not intended for your average user. If you screw up the paste or something, there's not much anybody can do to help you. I mean it's not *that* dangerous or anything, but be careful what you type is all I'm getting at :)
