It would be interesting to come up with a standard database access
layer for the Newton.
Ideally it would just look like a soup, so applications could use local
data or remote data without necessarily needing to know the difference.

Alternatively some sort of layer based around similar techniques to
JDBC could be interesting as well.
I've recently been working on something like this for Cocoa under OS X
for a program I'm writing for my wife.
