Hi Eric,
I disagree in some points.

Please notice, that you can build your own vision templates.

That's not true ! The VC software downloads a little program (myprog.txt) to
your RCX. This little program reacts to (8) IR messages send from your IR tower
to your RCX in that way you decided in the VC software (e.g. brake, play tone,
...)
You can download a NQC program to any slot you want except of slot 5, which the
VC software uses. If you edit the myprog.txt, you can switch to one of the left
4 slots and automatically execute the NQC program located there.
This was discused here before and Michael Gasperi puts this hack on his hombrew
sensor site. Have a look there, it's described in detail.

See above and Michael Gasperis homepage !

P.S.: I had a look at your robots, incredible !! Do you earn money with this ?
