Record Video Chat Interviews

A client of mine (celebrity) would like to record video interviews they are going to be doing with people all around the country. We are thinking that we will be sending out some basic equipment (web cam + microphone) to the people involved in the interview if they don't have the right stuff.

I'm trying to figure out what software we will use. It looks like ooVoo provides the split screen capability and ability to record and I've seen a couple instances on YouTube that look okay. I've personally not used ooVoo, so a bit worried about recommending it.

Are there other solutions that we should look at?

Any other thoughts on how to handle this?

Likely the site and videos will get some decent traffic because of who is involved and where they will be discussing the site.
