[execnet-dev] how to remotely open a program on win box?

[Charles Solar]

mm, well having a python window pop up is a bit suspicious.  Maybe the
popen io is not connecting correctly.
Maybe before trying the advanced process spawning service I wrote up,
try the basic 1 python instance service that is in execnet's script
directory.
