gmond by design is able to work without a configuration for exactly this
reason.

the default TTL for multicast packets is "1" and the default multicast
address should work independently on each VLAN as far as the clusters are
segmented by network (a usual setup in HPC), and your switches are configured
to handle multicast correctly and have no bugs.

as others had pointed, this is better handled by a configuration management
utility, specially if you are stuck with that OS that needs cygwin and that
wouldn't do multicast (from their release notes the beta version of cygwin 1.7
will be able to do multicast correctly in Vista/2008, but haven't really tested 
it)
