Whatever Origin is an open source alternative to AnyOrigin.com
When I was facing Same Origin problems while developing Bitcoin Pie, I was excited to discover how anyorigin.com solved the issue for me ... only, a week later it stopped working for some https sites.
For example, right now try and feed https://bitcointalk.org/ into anyorigin and you'll get an ugly "null" as the output.
Having recently discovered Heroku and Play!, I found that deploying a simple server app is no longer a big deal, and so made out to develop a simple, open source alternative to Any Origin.
