Sure, but in such a case you would need to obtain a source distribution
anyway - if only to recompile any native code (or bindings to native
code) it might contain or to produce a egg for that platform.

Yes, see above.

End users use binary distributions and don't use or care about tests.
Developers, porters and packagers use source distributions and do care
about tests. So, ship them with your source, but don't bother with your

Or, to look at it another way, if your users need to run your tests, you
(or your linux distro) have already shipped a broken binary.

Mozilla has a large suite of test cases. Do you wish they shipped those
so you could run them every time you download Firefox? If they did,
would you?
