Network Sync in OSX

Hi,

Im trying to use the network midi sync built into OSX's AudioMidi prefs, but
im having some issues.

I have the connection right, Im creating a link, but and one cpu is
recieving signal from the other.

But it seems that the receiver is not able to get the song position past
beat 2 of measure one, without returning to the beginning of the piece, and
continuously doing that.

Also, it seems to be requiring a lot of cpu for such a seemingly small task.

Is there a better protocol, that is a standard for this type of thing?

I wonder in relation to max and other programs.

btw, I know of max's abillity to do this over tcp and others, but Id really
like to use this OSX thing or another standalone, as Id like to send/recieve
from other apps also.

Thanks all,
Computo
