FPSLIC seemed like a dream when I first tried to use it, but
the tools are really bad (maybe they are a little better now)
Atmel claims the pricing starts from 7$ but only the 94K40 devices
are available (from digikey 45$) smaller devices digikey pricing
is $14 but non stock, and no idea where to get in small quantity

and the software licensing is really a killer, I spend 2 weeks
troubleshooting the license (involved phone calls to us support)
and then it times out all the time. So I dropped FPSLIC at least
temporarly from my desk.

A Spartan that can hold AVR core and same amount of logic as AT94K40
costs less than AT94K40, so why bother with FPSLIC?
