Since people seem to see the necessity for some more functionality 
within plugins, i want
to present LACPA (Linux Audio Cluster Plugin Api), which was intended to 
be the
plugin api of the linux audio cluster (which i never finished due to the 
lack of time).

Its main features:
* usable for midi/audio plugins (one plugin could be a host for other 
plugins as well)
* sampleaccurate timeinfo for sequencers, tempo-synched 
effects/instruments, video
* fixed size audiobuffers (good for use with networks and frequency 
domain effects)
* extensible while keeping binary downward compatability
* no dependencies between host's and plugin's gui (plugins guis are 
supposed to run in their own process)


BTW, by adding a control type "message", the realtime message part of 
LACPA could be easily
added to LADSPA without breaking existing hosts .
