After a some downtime to think about it, this is what I've come up with for the 2nd version.

New Features

1. Voice recognition (complete with R2D2 beeping)
2. Smarter Search (handle misspellings, I call it the C3PO feature)
3. Put it in a refrigerator (with a darth vader sticker on it)
4. Touch screen (with jaba ooze)

System improvements

1. Redo the user interface. It is too light, it needs more contrast (Needs more darkside)
2. Replace the relay boards (maybe vader's chest?)
3. Remove the air pumps
4. Make the system DC instead of AC
5. Better administration tools
6. Better drink auditing
7. Better user auditing
8. A wiring harness
9. A terminal block for power
10. Set up line clearing in areas where it only needs to be
11. Make clearing the lines a bit easier. This is after I had a stream of rum shoot at me at Maker's Faire.
12. Dedicated Computer
13. Make the system waterproof. (don't want the force to shock me )
