Have done that in a school project, deadline was kinda close and we'd done zip for it, so I decided to just solo it, but eventually dragged in 50% of the team. Usually was the case in school for freezing out others (well was one group where they excluded one, but that was race, heh) not some sort of "you can't handle this, untermensch" attitude.
Realized the client wants something hinted at in the spec (yay for craptastic project management) and that something is really, really, really nasty to implement. Have no idea on how to do this, so typical Monday, heh.
