Sure, it's simply a Python-wrapped visualization app that I want to interact
with remotely -- I send Python cmds to the app from a client, they get
executed, an image is generated and returned. Because I want it to be
*interactive*, I'd don't want to write a jpeg file to disk, but simply keep it
in memory and return the binary stream.
I realize a big question is - what sort of protocol *should* be used. The
answer is not a simple one, due in part to other groups/apps I'm trying to
interface with. FWIW, I've used CORBA til now, but am dumping it, again, for
various reasons.
thanks for asking,
--Randy
