Randy and I discussed this briefly, and I think there are two approaches
we could take post-Preview to this.

One would be to change Chandler to create random UUIDs for events
imported from iCalendar.  This would probably fix the problem Randy
describes for iCalendar data, but it wouldn't solve it for the general
case (if I publish a public event as EIM, say).

Another approach would be to change Cosmo's storage model.

In the fullness of time, I'd prefer to change Cosmo's one-UUID-space
model.  This would obviously be more work, but I think this is the root
problem.  If Chandler and the Hub are successful we're not going to want
everyone having write access to anything they can determine a UUID for.
