Great, thanks.

To give you a sense of what's possible, here's a python script I
am using to run commands on a windows VM:

--8<---------------cut here---------------start------------->8---
#!/usr/bin/env python
from subprocess import Popen, list2cmdline, PIPE, call
import sys

p = Popen([
  'winexe', '-U', 'win7ult32/dave%mypassword', '//Win7ult32', 
  ' && '.join([
                'cmd.exe /q /c set GIT_PAGER=',
                r'net use s: \\vboxsvr\src /persistent:no > nul',
                +' || exit %errorlevel%'

    retcode = p.wait()

--8<---------------cut here---------------end--------------->8---

This has been working very reliably for me [note:
subprocess.list2cmdline does *windows* cmd quoting, even when run on
Posix].  I can type, e.g.,

--8<---------------cut here---------------start------------->8---
winx command1 \&\& command2
--8<---------------cut here---------------end--------------->8---

into my posix command shell and it will run those commands on the
windows machine almost instantly.
