I'm seriously thinking about using a modified CODA system on Linux to create
a truly distributed object database for Zope, which could be a good basis
for a distributed "Python-Pan" system.

The other issues such as installation tools still need to be considered, but
I'd sure like to tackle this problem using CODA or perhaps AFS when its
open-sourced this month by IBM.
