For pywin32, my understanding is that (ignoring start menu stuff) the
postinstall registers the DLLs for COM and things like that. Which is
essential, but only for the system installation (you don't want every
virtualenv registering as "the" Python COM server). So pywin32 would
need work to make it virtualenv-friendly anyway, and while that's
being done, it can probably be made wheel-friendly too. For now,
though, my experience is that using converted wheels in virtualenvs
works fine as long as you don't write services or COM servers.

But anyway, pywin32 isn't hosted anywhere pip can find, so "pip
install" doesn't work from sdist either.

Thanks for the information, nevertheless.
