sync two powerbooks?

[Daniel Rubinstein]

I finally got my work to by me a 12' PB - it is adorable! was worth 
waiting for it for 9 months! Now my question is how do i sync the 12' 
with my old 15' PB i keep at home? I would like to sync my documents 
folder which is about 1.3GIG. They are both connected to a broadband 
router and i am looking for a way to have an automatic sync which will 
update the data between two machines. Is there any app out there that 
will do it?

Thanks for your help,
