You mean two authors collaborating on one article? I believe you have to choose one or the other for the markup.

Yes it looks like the whole authorship thing only offers 1:1 authorship Me thinks Google will evtually offer something to deal with multiple authors.

Yeah Google only works with 1:1 so maybe if you setup a Google account shared by both users and markup using that profile is the only work around I could think of, but could be messy.
