It can, but only when both extremes of Vdd are well below the voltage 
level of the USB but, which can be below 4.5 V. I would not call that a 
true 'production' grade programmer.

OTOH, with a very limited interpretation of 'extremes', all 
target-powered programmers could be considered 'production' grade....

Wisp628/648? OK, maybe that is a cheap one :) but what about an ICD2?
