Would it be possible to "Modularize" the Myth calls for recorders, so
you have an IVTV Module, a Firewire Module, a DVB Module and so on?
This would make it pretty easy to make a "Linux Firewire Module" and
an "OSX Firewire Module" (And, say, a "Solaris Firewire Module" or
whatever else people want to do) and to dynamically link them in at
runtime (So if you get a Firewire HD box, you don't need to completely
recompile Myth to use it, just compile the Required Firewire module,
drop it in, and restart MythBackend).

Just an idea. Would make for simpler additions and upgrades in the
future, and would make the code easier to debug (Easier tracking down
the problem in a small, isolated module with a simple "Test Client" (A
"Fake" backend that connects loads the module and pokes and probes it
'til it finds the data/command call that broke))
