1) The biggest issue with sharing projects is the relinking to media. It helps if the computer name or the media drive are named the same on both computers. Otherwise, you’ll find yourself relinking a lot. Render files will need to be recreated.
2) Always Zip or Stuff project files when you send them via internet. It protects them.
3) Multiclips sometimes do not survive well in shared projects. So, if you have many multiclips, you may be in for some headaches.
