OS: pretty much any Unixish OS, though on anything but Linux, BSD, and 
Mac OS X (and maybe Solaris) you may run into some small problems. Also 
Windows.

Hardware: anything with enough juice that can run your OS. Not very 
specific, I know, but it all depends on the performance you need. Less 
than .5 hits/sec and pretty much anything that'll load Zope will work.

Sure. Why not?

Almost certainly. There are a few OS-specific Products, though, but that 
only matters on the ZEO client (except for storages, which only matter 
on the ZEO server.)

You don't even have to match versions, save for sanity. ZEO is not a 
tightly-coupled communications protocol. Consider:

Windows
   Python 2.3.4
   Zope 2.7.5
   ZEO client - SomeProduct 1.1

Linux
   Python 2.3.3
   Zope 2.7.3
   ZEO server - no products
   ZEO client - SomeProduct 1.0
     ZEO command line client, for debugging

This would work fine. All three ZEO clients would have the same data 
(that from the ZEO server), even with different software.
