no... -V tries to figure out what service is running on the port, in
this case it will just print "ident?" since the bots don't actualy
implement a full ident server.

if you run nmap -p 22 -V on a machine running ssh you'll see what it can do.

also, you might want to try the nmap options
--min_parallelism 100 --max_rtt_timeout 50

where "50" is what you know the max round trip time for your network
should be, and "100" is the number of ports to scan at once.

A full 1-65535 scan on one host, or a single port scan on the entire
network finish in less than a minute with those options.
