The perl Net::Ping module had a similar problem (see
http://www.perlmonks.org/index.pl?node_id=42739 for details).

These suggestions were implemented by the creation of the
Win32::PingICMP module which taps icmp.dll to circumvent the "you must
be admin" limitation.

I have neither the ability nor the desire to look in to recreating in
cygwin what icmp.dll and Win32::PingICMP do for Windows and perl.

I'm just letting other folks know that it is probably possible and
perhaps not that painful.
