I am sure many of you have heard of XIPWIRE in the news recently for their support of WikiLeaks. Turns out, they handle donations for a number of nonprofit organizations. I believe this would be a great way to allow users to support Bitcoin - in addition, XIPWIRE is a promising USD<->BTC intermediary.
While I am willing to help establish a XIPWIRE donation account for Bitcoin, perhaps it would be more appropriate if someone else (Satoshi?) set up the account.https://xipwire.com/info/nonprofit/howitworks/
