Advice on Partnerships

I would like to be able to share expenses and work on my experimental
aircraft now and in the future. I would like to have a partnership with
several others both to build and to operate an experimental 4 to 6 place
aircraft. Perhaps, especially in building, this is not advisable. I
would like to find out if there are any materials on line, or in print,
that detail the pitfalls and pratfalls of experimental aircraft
partnerships.

I am already a partner in a 172 with five others...perfect for cost
sharing, but I want the experimental experience/performance etc.
