Good idea, but for now I use instawallet also. I loaded btc in IW's for xmas gifts and send the url to the lucky recipient ... boom done boom!
technically, this works, of course.
But that cant be all of it.. Trusting a single company/project/website, its availability, accessability, honesty and all. Went wrong too often already. Yes, I use Instawallet too. But the future *must* be p2p-exchange, OTC-exchange, mixing cascades, and, consequently, direct import/export of single keys to transfer bitcoins "offline".
Else, we could keep using bankaccounts, papermoney and paypal, not? :-P
