Perhaps if you were able to leverage it into performing tasks that the specific data structure excels at where other things don't.
I'm kind of thinking along the lines of google's BigTable and Mapreduce but that isn't exactly the same.
Document its pros and cons well (advertisement), make an easy-to-use library with a clear interface (product), spread the word to the target audience (marketing), and then monetize the _publicity_, not the data structure itself.
