Well, I think it's reasonably portable, I think your program might work,
and it does mainly expose the underlying OS.
You wouldn't need a separate OpenTransport version for MacOS, because
MacOS Python supports sockets. So far, so good. I haven't run Python
on MacOS for a couple of years, but I bet you could use select() with
multiple sockets just as on UNIX. Now, as long as "does things with
the data" doesn't require the dread User Interface, you're set.
Realistically, though, it's a little queer for a MacOS application
to have no User Interface, or a tty-like console window. In practice
I suspect that there aren't many Python applications in actual use that
run across platforms without any platform-specific tweaks - is that true?
