Wirecast to wirecast
I would use skype from the remote location into the local computer running wirecast then use their screen capturing option to capture the skype video. 

The pro version of wirecast allows and input to be RTMP, Web streams and IP cameras. Assuming you have that, you could stream from the remote wirecast and bring it in as a source on the local system.

You may already be aware, but this will add a major delay in the remote feed. Because it will have to be encoded twice. Once from there to local then again locally on your main feed. Just something to be aware of.
