So, what is wanted or needed? Don't tell me we have a standard, some development tools, but no ideas for the actual product! [SLAPS HEAD]
edit: Ooh, ooh. (picture me with hand up)
What about a plugin that spits out a serial strings to control other equipment? (projector, screen, whatever)
How about a network interface to remotely control the jukebox? Would you even want to?
Loadman, are you doing a LEDWIZ plugin? That's probably the most useful one I can think of.
