syncOtunes

Barb got the scoop on this over at Engadget, but I
beat her to the punch over here at tuaw.  ;-)

syncOtunes is a nifty little piece of freeware (although donations would seem to be welcome on the site) that autosyncs the iTunes Music Libraries of your two computers into a separate folder sans duplicate songfiles that can easily be imported into iTunes via an included AppleScript. There is even a time-limited test version of the software for all you people out there on Windows or those of you busy straddling the Switcher-divide.

As a side-note, syncOtunes is coded in REALBasic, which is a pretty good cross-platform entry level programing tool for all you coding n00bs (like myself), who remember the days of
real basic BASIC (ah, the 80s!) and want to move beyond the world of AppleScript.
