...there are technical reasons for all this:

1. pdp runs in it's own thread, and the quicktime sequence grabber  
Idle() needs more time than it's given in pdp_ieee1394_thread(), so  
it winds up blocking or something...I've looked at this, but haven't  
figured out a way to make it work...good news is that you can go  
ahead and use pix_video in gem and pix_2pdp with very little cost...

2.  pdp_ieee1394 is mac only, so yves doesn't need to distribute it  
in his linux archive

3.  pdp by itself doesn't use opengl:  that functionality comes from  
3dp...otoh, opengl is gem's bread and butter...

...personally, I've not crosstested to see how pd/gem/pdp/pidip/ 
gridflow fare against max/msp/jitter/nato, but I'd imagine that it  
more than holds it's ground except in documentation ;-)
