Excellent idea. I'm all for it. Then it would also be easy to prepare a
midnam file (for the General Users soundfont for instance) for use in
certain DAWs.

This would be a powerful feature allowing for inserts directly from
fluidsynth into a live mix. Would this entail a significant CPU
overhead ?
Even so, this could still be very effective on dual- and multi-core
machines. 

Could LADSPA plugins be easily incorporated in the same way as the
chorus and reverb effects in multichannel mode or would this require a
major overhaul ? In other words, how do fluid reverb/chorus and LADSPA
fit in the audio signal chain. I imagine the current signal path to
resemble something like this

noteon --> chorus/reverb --> --> jack output port --> Jack Rack --->
LADSPA --> ALSA 

...or is this incorrect ? 

I don't see how the two effects ports fit into the whole scheme. 

LADSPA functionality in FS could be effective when using FS in live situations 
while
for recording LADSPA could be used as inserts or sends from within the host DAW.

Yes, an official testing branch could be a nice way for testing new
features before they could be merged.
