screen alternatives on NT

hey,

I was wondering what options NT users might have for 'screen'. In particular, I wanted
an application that multiplexed terminals on the NT side (via cmd) was able to edit 
the buffers they produced, and was able to launch NT applications...

Anyways, I've cross-posted this to the xemacs-nt and xemacs-devel mailing lists, because
I think that xemacs might be an acceptable substitute (assuming a screen NT port doesn't
exist), and had a couple of questions for them:

	1) does a 'screen' keybinding for xemacs exist?
	2) if not, what are some good pointers on creating one?

In particular, I find that the screen keybindings are especially friendly to people who 
run quite a few shells:

	1) 'C-a c' vs 'M-x shell' to create a shell 
	2) 'C-a <sp>' vs ?? to cycle shells.

etc. etc. etc.

Anyways, any help on these questions would be greatly appreciated.
