That's awesome!  So much better than starting from scratch.

Yep...my current thought right now is have the CI or something like it act
as a 'master' server any number of 'slave' servers, and have the master
give a slave a given subset to run and have it report back when done and
then give it another set to run until there are no more tests to run.  That
way we could spin up 2 or 200 and ideally it'd Just Work (tm).

I'll play around with a linux-based VM in vagrant and let you know.

I have limited experience, but working stuff, running on Windows GUIs
automated using Windows Server 2003 R2.  Windows Server 2003 because it's a
legacy app that needs admin privileges for no particular reason, but I
didn't have source code...ugh...don't ask ;).  I had to play with the local
security policy settings or something like that and have it automatically
log in as the admin user so the desktop was always there, but it *does*
work.  The nice thing is flex and/or mustella will work fine as a normal
user, so I should be able to make it run on Windows Server 2008 without any
UAC-related troubles.

tl;dr Meme version:

I don't always run automated Windows GUI stuff in the cloud, but when I do,
I make it work :)
