Suppose I install srfs on both my laptop and my server.  I then
move the CVS repository for my pet project onto the new srfs
filesystem and I take off for the weekend with my laptop.   Over
the weekend I commit several changes to file X.  Over the weekend
my friend also commits several changes to file X.

When I get home and plug in my laptop, presumably the caching
daemon will try to stabalize the system by deciding which version
of file X was changed last and replicating that latest version.  

Who's work will the caching daemon overwrite?  My work, or my
friends work?

Of course, this need not involve anything so extreme as days of
disconnected independent operation.  A rebooting router between
two previously syncd srfs peers seems sufficient to trigger this
kind of data loss, unless you make the logging daemon fail all
writes when disconnected.
