Synchronize: list of files + exclude patterns

What do you think about the synchronize acting like this:
1. build a list of the files that have changed (on local & remote)
2. allow to remove files from that list
3. synchronize remote and/or local

And what about being able to define some patterns to not synchronize? I'm thinking at the CVS folders for example.

It is already on the wishlist, so please be patient :-)
