Well that raised a smile!  So far it builds _and_ works pretty much just 
like the real thing. The loss of allcaps is no big deal - using gid 
works just fine. From an audio perspective, I figure there's not a whole 
lot left to actually test regarding realtime lsm. It does what it's 
supposed to do (very well).  To all participants in the development (and 
debate), well done!!

cheers, Cal
