[ale] sync desktop and OS X laptop?

[mpwright at speedfactory.net (Mark Wright)]

Does anybody have an idea how to do a windows style briefcase setup  
for a Mac laptop and Ubuntu desktop.

It would be similar to syncing a PDA I guess.

I would like to make my /home/mark on Ubuntu and /Users/Mark on OSX  
sync up over ethernet so that all my email and the contents of my  
documents folders are mirrored.

Any ideas?

Thanks

Mark
