Hello,
We have a Core Data app running on 5 computers. We've used a
variety of kludges and nasty overkills to keep the data
consistent on the shared sqlite database. Now, however, it
appears that we will need some kind of notifications for
critical inventory changes to the database.
I implemented a NSDistributedNotificationCenter notification but
realized it was not as distributed as I had thought (only
intra-machine). I prototyped Distributed Objects but after
setting up a connection and a server protocol, I couldn't easily
get the proxy object from one machine to the other and thought
it didn't look like the right mechanism anyway (no notification,
too client-servery, not peer enough by default). Sync Services
is a possibility but I really just want a notification - not a synchronization.
What approach do others use for inter-machine peer notifications?
Thanks in advance for any helpful comments or sample code,
Steve
