Has anyone ever done this?

There are similar things done in the property world:

1. Some New Homes developers keep a 25% share of the property when the sell it, so whenever the property is sold on the take 25% of the sale price.

2. Sometimes when land is sold without planning permission and is then sold again or the new owner gains planning permission the previous owner recieves a cut.

Just seems a few pitfalls to be had.

You could add a clause that you get first refusal to match any offers for the domain.
