host check through 2 isps simultaneously

[Ethan Galstad]

Actually, Nagios doesn't care what kind of address you specify for 
the host.  Nagios simply treats it as a string and passes it off the 
plugins for their use.  There's nothing stopping anyone from putting 
a MAC address in that field, multiple IP addresses, GPS coordinates, 
or text directions on where to find the server. :-)  

You could set the address field to be "192.168.1.2,192.168.0.5" to 
indicate that the host had two IPs.  Your host check command (and 
service plugins) would then have to properly parse the address field 
to pick out the individual addresses to be checked.
