Thanks for this question, here are my initial thoughts...  I'm hoping 
some of the other technical suggestions people have made are helpful, 
because I don't think this is a viable path.  I'm not sure how many 
other communities handle this scenario, but I know when I was at 
Eclipse, for example, projects were discouraged from endorsing products 
in this manner.  Moreover, submissions advertising goods or services are 
discouraged in our web site Terms of Use.
