This is one of the main reasons that I'm not using Git at work, there hasn't been a super solid way to get the Github functionality on an internal network where it's 100% secure. This is a REALLY smart move for the guys at Github.
agreed. I don't feel comfortable uploading all my code to a third party, which in this case is even located in a different country I'm not familiar with the legislation details.
I'm using gitosis and redmine internally now, but this one is really interesting
Not to be pedantic, but there's no way that you're going to make anything 100% secure, even if you host it internally. I do agree with your point though and can understand some companies wanting to keep all of their code in-house though.
