I just did that...
I am using sync between layer in machine 1, and they work well, but layers on machine 2 don't synchronize to the ids in machine 1, I am obviously not repeating sync Ids on both machines, what I mean is that certain layers on machine 1, have sync ids from 1 to 5, and certain layers on machine 2 have sync ids from 6 to 10.

I just tried, didn't work, enabled apple talk, tried again, and still doesn't work...
do I need to restart after enabling apple talk????
has anyone done this before succesfully????
