Awesome! thanks for the reading material :D

1) The problem supply can be tackled in many many ways.

2) The verification problem is exactly why I stated NP as a problem class where the verification process is often relatively simple and straight forward. Obviously if that isn't the case then perhaps the problem isn't that well suited for this kind of environment.

3) The bandwidth issue is not something that I had considered. Makes absolute sense when you put it that way.

Just for reference, don't forget that NP behaviour is displayed asymptotically. Checking a solution can still be pretty costly.
