some LSpushDevice ...
So I can have a scan on remote subnets so i can see the MAC address for devices that do not scan any other way (ie no ports open)...
Or a remote agent that can run on remote servers on remote subnets to assist in scanning for devices on those subnets.
[edit]
come to think of it, I wonder if just the "service" part of the Lansweeper could be installed somewhereon a remote subnet and just configed simple to say ,only do device scanning and only on this subnet.
basically a stripped down version of lansweeper that just uses the remote sql database .
