Well, it doesn't exactly make the code portable on the binary
level... *hehe*
IMHO, pure DSP plugins should load and run on any machine with the
right CPU, regardless of operating system, provided someone writes
the required object file loaders. (That's actually theoretically
possible no matter what the plugin does, but it's *slightly* harder
to emulate an entire OS than to just provide what's required by
plugins according to the LADSPA API spec. ;-)

That's why GUI plugins and DSP plugins should be two different,
separate things, connected through the host. :-)
