That script may not be portable to other routers (or even work on some simple routers or that don't support SNMP). Nor would the router know about MAC's that haven't passed a packet through. But it gave me a good idea.

Assuming this all on a local net and the subnets are not firewalled from each other (ie. no firewall between the local subnets - Firewalls between the local net and the internet would be fine). Just ping each ip in the net. If this is your local net you should have no problem getting the network info.

Then all you have to do poll you local ARP table. Which far easier than wirting a custom router poller.
