I like the idea. I had been thinking of a picture browser, akin to 
gqview, but that entails a lot of image-processing stuff which would 
swamp the more general aspects of an app.

However, rather than using ZDBase I'd very strongly suggest looking at 
the tuplebase stuff. It manages freeform tuples rather than records 
from fixed-schema tables and all access is transacted, whereas ZDBase 
requires careful locking. The ZTB API and semantics remain the same 
regardless of the actual underlying implementation (locally hosted or 
via network socket to another process or host).

It's been a couple of years since I've had a GUI app in development, so 
this examplar would very helpful in getting the ZooLib UI code updated 
-- it's become a little crusty in places (see TODO.html for specifics), 
and some architectural issues arose that I think I've now got solutions 
for; it would be good to work them out with new code that's still 
maleable.

A+
