check_by_ssh? I'd avoid that at any cost, ssh is too powerful, it's the 
equivalent of nrpe with the "don't blame me flag if you get hacked". If 
you can't use nrpe, then you certainly can't give out ssh access.

Also, I'm not sure it's worth writing any wrapper, since any which way 
you'd still need a remote execution mechanism. By the time you have any 
remote execution mechanism, then surely you should use the standard 
check_ntp plugin...

I think that SNMP, NSCA would be your best bets, but if you can't have 
anything, there is also one more remote possibility. Timestamping 
through ICMP. Long shot but it can be done, you'd probably need to write 
a custom plugin though and if it's a tight environment then likely this 
would be blocked.
