I would like to mount this display remotely from my computer. That's why I'm wondering if I can get power from the serial cable to power the display. Otherwise, I'll find a wall wart to power it.

Looking int buying one of these...

just a few ?'s.

Can I navigate through MP3's, start, stop, etc. in winamp with the keys included in this kit and the software that's available around the internet?

Also, can this unit be powered off of the serial port?
