Can those odbms handle heavy load ?????????
I only have experience with O2 ... and it was 5 years ago. Well ... it 
sucked. Nice concepts in O2, but not strong enough and fall under heavy 
load. But that was 5 years ago.
And, once again ... I don't want to use proprietary sofware anymore 
without a VERY good reason.

And what about scalability when using small objects and going from 200 
000 objects to 2 millions ?
Any benchmark ?
