Just give it a name that isn't already a commonly used sound in music, so that it's possible to search for clap plugins etc. without a whole bunch of useless hits, and to search for information on this format and VST without getting hits for plugins that make clap sounds. There's no reason to choose something that is going to be a PITA down the line. CLP, as mentioned earlier, is already a much better suggestion. I mean, you wouldn't call it "DAW", "FX", "SYNTH", "GUITAR" or "PIANO", so why call it clap when that's a super-common search term for people looking to work on music? There really is no reason to choose a confusing and ambiguous name.
Changing the name now is no biggie, but you need to do this before the genie is out of the bottle. Won't somebody think of the users and making it easy to search?!!?!?
