Is it somehow possible to sync data on two mobiles phones I am using a Samsung Galaxy S (running Android 2.1) mobile phone and am thinking (only thinking mind you) of bying a Samsung Galaxy tablet (this one running Android 2.2).

I am wondering: is it somehow possible to sync the data used by programs on these two devices so that software (like the marvelous Book catalogue) can be installed twice with the possiblity to copy the databases used by these program to both mobiles/tablets ?

Preferably by copying them over using WiFi or so.
i've one found so far paid solution, but there is a 30 day trial to check it out.
