Portable Ubuntu Remix.
Its a great trail, the project allowed that, to run Ubuntu from (on) windows, just like a native application. And the project is claiming that, one can install Ubuntu applications from synaptic manager, and ubuntu access the filesystem(drives) directly. Probably it will become a development platform, just like cygwin. You can see the project here. http://sourceforge.net/projects/portableubuntu/ http://portableubuntu.demonccc.com.ar/ -srinivas.
