Hehe, I've finally manged to run Firefox running in OpenBSD virtual machine through Xming in Vista. Similar to what Xaero_Vincent is doing but in reverse (Windows is my main desktop).
I need this to get one Unix IDE because I'm doing smaller unix tool in C and I'm tired of WinSCP notepad.

On picture: IE7, Firefox on Vista and Firefox on OpenBSD (front window is BSD one).
Anybody else thinks theme of Vista FF looks worse than that of BSD FF?
