Well, speaking as someone who is actively using tla on windows, and 
working hard to make it run better, I can very safely say that tla 
*will* run on windows. Now, my personal itch is to get it to run along 
with cygwin, since that is a little easier to do, and I have long used 
cygwin, because it's a good tool. Since tla is command-line only right 
now, it seems reasonable that cygwin isn't a big overhead.

Getting a truly native version is probably a little more difficult, as 
tla uses the raw open()/close(), not the libc fopen(), fclose(), etc. I 
believe in win32 these are called _open(), and _close(). But really for 
windows what you want is a gui.

I know there is a goal of getting tla broken up into a library and a 
cmd-line wrapper, which would make it much easier to create a gui out of 
it. (Right now the wrappers all depend on forking a tla sub-process to 
get work done.)

actually, darcs looks like it might be quite nice to use as well. I look 
forward to seeing what it turns into. I really wonder why patch-signing 
would be difficult to incorporate into the system. In tla, we just added 
a file that said "here's the signature" and run a user-specified program 
(gpg) to sign it, and another user specified program (wrapper around 
gpg) to check the signature.

I can't say why this would be hard with darcs. Though I know last I 
checked they didn't have pre/post commit hooks, or other such goodies 
which also let you nice things.

I think keeping an archive of emails just so you can get signatures is 
pretty silly, since that means you have to email yourself every time you 
do a commit.
