I think the term for this guy would be 'multiplicator'. Getting him on board may have great benefit, only the way how to do this is delicate.
A completely configured cubie with 500nxt would seem a very good idea to me.
with a easy passphase with instructions to make a new account and transfer the 500 nxt to his new account with 30+ characters that would be a fun exercise for him and wouldn't take more then 20 minutes...i'm sure he would enjoy the hands on experience also.
