It syncs my custom products just fine.

Be aware that zsyncer basically:

- "exports" the stuff you're syncing to an in-memory pickle 
- transmits the pickle across the network
- uses xml-rpc to have the remote server import this pickle

So it's pretty much just a more convenient way to do import/export.
I mention this because import / export of large items can take
a looooong time.  I don't recommend using zsyncer to transer
200 MB of stuff at once, or you'll be waiting forever for
a success message.  I've done this and gotten success eventually,
but I feel a lot safer syncing in smaller batches.

There are also some thorny issues, like unless the system time
on the two systems is in sync, zsyncer will give you misleading
information about what is and isn't in sync.
