May I promote the nlnet.net foundation to you - I talked to them and they do now accept Bitcoin donations
I'm not in any way affiliated with them. Here's what they fund(ed) in their own words:
"NLnet has contributed funding to many important and very visible projects such as NLnet Labs, Jitsi
, the SSL Observatory, NoScript
, Tor, GPLv3, Serval project, Calligra and webODF as well as many other less known projects that operate more in the background. "
I'm especially a fan of Jitsi as an open-source Skype alternative, which they support.
So take a minute to have a look on their site. If you like them as well, here's the link to their donation site:http://nlnet.nl/donating/donate.cgi?for=foundation
