Or if anyone knows how to use an android phone as a wifi adapter for the Linux machine, that would work also.
You mean making your phone the WiFi hotspot and have the machines connect to it? In order to do that, you need to have that service on your phone. I have Sprint (Galaxy S), and in order to make my WiFi active to where people can use my phone and Sprint's network as they're connecting point, its like $30 bucks a month... my phone is in WiFi everyday, however, its due to other hosts (my WiFi at home, work, etc...),so I can't broadcast my signal to let others use it..
As part of a project in college I had to make Fedora Core5 a client of my Windows Server 2008 domain in Virtual... that was fun

.. I can't exactly remember what I did as that was years ago, but it can be done..
