Absolutly, but in this case you can just use FileStorage, since coda is
a filesystem.

I attended the Coda session at last year's Linux Expo.  There, the
professor in charge of the project gave a very clear explanation of coda
and how it works.

Useful results with Zope should be immediate, Simply store your Data.fs
file on a filesystem that is replicated by Coda.

There is a more interesting application however, and that is
implementing the actual coda protocols themsleves into a sort of
ReplicatedStorage (I'm not positive if that is the best way to slice the
pie, but it's an idea).  Another idea is to roll a similar or identical
protocol into ZEO, so that not only are Storage Clients and Storage
Server are distributed in a parent/child relationship, but also that
Storage Servers can be distributed in a peer relationship that replicate
each other to provide failover and replication.

Interesting stuff in any case.  I'd really like to hear about someone
who has a success story with Code and Zope using just it's filesystem
capabilities.
