Well, I've got the exact same feeling, like I'm going somewhere interesting, but I'm not there yet.
I feel like there's some generic solution waiting outthere,
I kind of met some of the problems that such solution would solve... but I'm having problems touching the solution or clearly defining the class of problems that it would target..

What is the architecture here? Peer-to-peer, client-server?
packets floating in a TCP/IP stream with a field in the binary format for "substream ID" or something like that would be doable.
That's all multiplexiing really is ... packets inside of some encapsulating format.
Pack/unpack is a PITA ... if someone has a good Perl-data-structure to binary implementation, I'd like to hear of it too, something like YAML (or even the dreaded XML) would be language agnostic, but you don't want to send that over the wire if you care about efficiency. Heck, you really don't want to parse it either. If it's Perl <-> Perl maybe Storable is okay, you could freeze a packet class or something?

Actually this is done quite often but we typically don't see it or think of it as multiplexing.. proxy servers being an overly simple example. VPN, etc.
Using perl for this should be fine unless it is time critical.
