Can I use iSync to "sync" up a powerbook (PPC) and a iMac (intel) on almost everything? Are there any exceptions. Files/Progs/Media etc. What are my limitation with sharing almost everything a computer can share?

On a related note, can I sync up just a playlist on my desktop itunes, and then whenever I add a song on my desktop it adds it on my laptop. Can I do this with iPhoto as well? Can I do this for specific folders that would be sort of "linked" like a mutual dumpbox <-> both ways.

Is there type of mac CVS feature that can be run through bluetooth, without internet so if 5 people are in the same room with Powerbooks/Macbooks/etc. that all have bluetooth could edit files.

Sorry if I overshot this forum's category with the end of my post, but it is somewhat related.
