Thank god i have a private nuget feed in my network with local packages (internal api's and dll's for it) and the most important nuget packages (elmah, json.net, ...)

http://docs.nuget.org/docs/creating-packages/hosting-your-ow...

It's pretty easily and makes you less dependent on nuget... It took me a half an hour te get it set up.

PS. I wonder if it's as easy to setup your own private rubygem feed :)
