I'm considering if forming a cooperative has value to others. For example, I have supreme mastery as an explorer in Forestry, Prospecting and Tailoring. So I can provide materials to woodworkers, metalworkers, and jewelers, and can tailor a broad range of light and medium armour. Having cooperative arrangements with pretty much any other vocation could be great, as long as it benefits all parties.
So my questions are as follows, and uses the assumption that I'm not the first to think of this;
1) What key points/rules drive the success of such an arrangement?
2) how do you make such cooperation reasonably fair/equitable? Based on recipe difficulty, material procurement, what?
3) How do you handle items created 'for profit' as opposed to for personal use?
4) Does this approach work, or in the end should I just develop and use my alts?
