In a Corp Environment, WAN IP is not needed info for us, but I know it is for others. However, I would keep it and ad LAN IP, that's a must.
This is a great idea! for the reason explained above: to avoid disturbing remote user and do transfer files on the fly. Most of my activity as IT i love to do it on the background, on the console: Commands. It is painful to call remote user's attention (wasting around 10 minutes, or waiting hours) to be able to work on their computers, when we can do thing right away that won't interrupt their jobs (and ours). This is essential.
Doesn't exist any kind of filter command for that, so when you create a Group Session, it filters in that way? It's a good idea. You can even spot Ghost Sessions (duplicated) in this way. I like it.
