i have added a quick hack to my pusher:
when all data was sent i just resent it. that means with brute force 
resend all geometry layers :-)
THAT fixes the bunny, however i have to do it *10* times until the bunny 
seems ok.
That may also be the reason for the missing texture coordinates with 
ppctest2, there are still no textures on the objects, but the scene 
looks already different. i just resent geometry, not bitmaps.

I didn't expect that UDP packets are lost even on local transfer!

This seems to be the central problem! Do you know how much complexity is 
added to the pusher if i want to get sure every bit is sent correctly?!

But i guess i'll have to do so, since you won't go from UDP to TCP. I 
would strongly recommend using TCP. If the transmission is so bad that 
packets get lost often (the only case where TCP is slower than UDP) the 
connection is too slow/bad for 3d data transfer anyway, since 3d data 
takes much space.
