We have Subsystem for UNIX-based Applications (SUA) component available in Vista Ultimate and Enterprise SKUs.

What does this component do?

SUA provides the basic infrastructure to run UNIX-based applications and scripts on Windows Vista (Ultimate and Enterprise) and Longhorn Server

How does this component do that?

It is a native subsystem residing on top of the kernel just like the win32 subsystem

To do all the cool things, we need you to download from web which supplements SUA and brings you all the goodness.  We have had web download available here. Please note that it works *only* for Beta 2 (build 5384) bits only.

Please try it and drop me a line on how your experience was!
