I am sure that quite a few people around managed networks.
I have an idea and before creating a brainstorm entry I would like to see if there is a public for it and if it could be extended even more.

I'll stop the blablating and explain:
Add a new field type on a contact which could either be an IP or hostname for a faster remote management. An new action on the call menu would appear like 'VNC contact', 'RDP contact', 'telnet/ssh contact' depending on the application installed.
