Hey, I think you can do it with syslog-ng
http://www.balabit.com/network-security/syslog-ng/Your going to need a nix box to run it on then forward it on using syslog-ng.
Or if you have universal broadcast address (*.*.*.255) enabled you could point it at that and have your data sent to every machine on that C class, however that makes you vulnerable to smurf attacks and its generally not a good idea to do that unless your sure nothing can get past your firewall to 255 from outside plus it will generate a load of extra traffic acros the network.
Generally not a good idea
