Collab files aren't anything new. If you search the internet, you'll find a good deal of files with two or more voices collaborating to whatever degree - in fact, one was uploaded to WMM fairly recently - see "Slave to pussy duet" by slutinmyhead for ideas.
Anyways, the logistics of voice collaboration are rather difficult, even over the internet. It's definitely easier for a group of people to work on a script and then have one person record it.
