If there's a dispute between you and one of your developer clients, who has the 15% of the money the developer's client paid him/her until the dispute is resolved — you, or the developer? I ask because this relates to the much-debated "who is your real client" question.

Do your clients talk to each other a lot? Work on projects together? I think I'd want to work on a project with someone before I referred a client of mine to them at a moment that I was too busy.
