I don't know if this helps yew, but best way to do it is to get everyone to record their parts using Audacity or something, and then the editor simply gets all those files and edits them together. Skype usually does the trick.
If you do it properly, it should all line up and little editing is needed (outside of editing out coughs or removing background noise and awkward pauses) and if the host / recorders feed fucks up you still have data from three other people.
IDK if you had a method in mind but this is what I use for my Nintendo site.
This is essentially what I had in mind.
