The 100mA limitation will probably be an issue for me, otherwise it seems like 
a good solution.  Is this 100mA limit based on the power-supply electronics 
on the board, or because it's the default power that the USB port can deliver 
w/o the software explicitly requesting more?

Is there a relatively simple way to modify it so it can deliver more Vdd 
current?  I know my apps can take UP TO 180mA, though I'm not sure it will 
need near that much in the short time that the application circuit "runs" 
between power-up and the start of programming.

Cheers,
-Neil.
