It would be nice to be able to probe remote subnets/IP ranges for available Hosts in the MRC (without any Central Server requirements).
MRC Peers does this for the local subnet, but you can't probe other subnets.
This was a feature since the dawn of computers with pcAnywhere.
The ability to program/save those subnets/ranges would really help out those who are on the road frequently and have a lot of small clients they VPN into.
