The principle we follow is "design once, generate many". We are aiming on 
building any kind of plugins or audio backends our users want to build using 
the CLAM framework. See: http://clam-project.org/wiki/Network_Editor_tutorial

One of those targets is building VST plugins *for Windows* (crosscompiled from 
linux or natively from windows). The main advantage for linux users is that 
they can visually build their plugins or JACK applications in linux with 
CLAM, and then, if they want their plugin to be available for Windows users, 
just click a button and you'll have a VST plugin as well.

LV2 is also on our roadmap, and I guess that having already support for Ladspa 
it won't be that difficult. But right now our interests where VST just 
because a project partners asked us for some vst's and, well, it was funny 
doing that from linux. We had vst code working for a couple of years but 
without GUI, and in order to make this code valuable we had to unlock the GUI 
front. That's what we did.

The good news, if you are interested in AudioUnits, is that one of our 
coworkers, Ferran Orriols, already has an assigned time slot to implement 
AudioUnits in CLAM, after his eastern exams.

Of course, any help on supporting whatever plugin/backend platform would be 
very appreciated as we have a limited number of hands. ;-)
