I ran skype alongside a RemoteRig set-up to control an ICOM HF transceiver that had audio and video output for several years. It is as simple as calling in, having auto-answer set (in my case exclusive to known contact), and enjoying the feed. This combo gave me visual confirmation via Skype of the POTS line or IP based RemoteRig control - i.e. frequency, signal strength, etc..
In my case I used a USB Behringer interface which took the transceiver audio/visual feeds into a Panasonic Toughbook running Skype. That system stayed online 24/7/365 for several years. Actually, it is still in use - when I upgraded the ICOM HF transceiver, I lost video output and Skype was no longer needed.
