The major issue for the NC version is that it is old. However, I've done  
my share of pestering David (and only buying 1 (one) commercial license),  
so I'm hesitant to ask him for favors here, especially since I have the  
full code. I'd *love* to see an up-to-date OmniBase for Squeak, though. If  
only to expose more people to this wonderful piece of work.

The commercial version is up-to-date, I haven't checked whether the Linux  
version has file locking in there, but if it doesn't, as I said, it's a  
small matter to get it in (mostly testing).
