Quick (?) LCP question:
how closely is it tied to LADSPA?
Does it only support LADSPA float ports? (I guess it would.)

This is pretty much exactly what I'm thinking about right now... First
thought: Extend it to support XAP. Second thought: Turn it into a
more generic "remote control" API/protocol.
Then I started thinking about Audiality exporting it's mixer controls
to this, as a two-way alternative to the NRPN based protocol I'm
currently running over the ALSA sequencer or other MIDI API.
The fallback plan is to use MIDI over the ALSA
sequencer, but
I really don't want to have to do that!
I considered that as well, but there are two major issues. MIDI is
basically a one-way protocol. (There *are* standardized exceptions to
this rule, but AFAIK, none of them involve registering controls and
stuff like that.) MIDI has only 7 and 14 bit controls, no control
registering protocol etc, so one would have to design a new protocol
on top of MIDI, based CCs, NRPNs, SysEx or whatever - and at that
point, one starts to wonder what the point is in using MIDI as the
transport layer in the first place.
