I'm wondering a couple things about this (I'm primarily a Linux user):

1) If I write a Python prog under Linux, can I cross-build it as a
Windows executable running py2exe under Linux?  Does the exe have a
reasonable chance of being useable on a Windows system immediately, if
I don't have a Windows system to test on?  

2) How large is the .exe file typically, if the Python program isn't
large and doesn't use a lot of modules?

Thanks.
