Following you guys for a long time.
I am web developer for 3-4 years and I can really recommend the github solution. We are using it at work too.
If everything is up first, it will be pretty easy to update without any work and it is really stable.
Feel free to contact me if you need any help regarding github.
btw.: does anyone has the documents of the wiki for me to download?
Really need it for our LAN at weekend.. :D
