I don't see why you would want a Nxt VM script to "output an email" (or do anything else outside of the blockchain for that matter) - you do understand that whether such email was actually even really sent simply *cannot be proven* (as you are dealing with SMTP rather than a blockchain)?

Also SMTP is going to require accounts that need to be signed into and you don't want to end up with people effectively running "relay servers" or they'll end up on email blacklists.

Wouldn't it make more sense for such things to be services instead?

About walking vs. running - you are getting far too excited jl777 - can you just take something to slow down to a pace that we can keep up with (by the time we've tried to discuss one of your ideas you typically have posted 3 others).
