why wouldn't you just run secureCRT? I mean, I like the linux desktop as much as the next slashdotter. But if I'm forced into a windows machine at work (I am) just run a windows terminal. It works fine, has tabs, fowards X, all that stuff.
On yeah, and get Console2 to replace the normal command console that windows has (OMG - resizable windows!?). And there are a number of GNU tools compiled under windows to run a shell (bash, vi, ssh, grep, awk, etc etc)
(they're old, but they work)
(also old, but works)
I've combined all three to get a useful windows machine.
