And this occurs in the proprietary software world as well.  On two 
instances in my career a customer pays a vendor to modify their product 
in a certain way.  The vendor continues to own the product in whole, the 
customer simply now gets a release that does what they need--and all the 
vendor's other customers get that improved product as well.

(My involvement was with unrelated vendor/customer pairs, once on the 
customer side, and once on the vendor side, and so I'm sure this is not 
an uncommon occurrence.)
