I'm with birger...I think that the real value for you would be to get people to place tickers on their site, but for each ticker to have a "powered by w-shadow" statement and a direct link to your site... use it as an SEO strategy then offer extra value products.
An example of what I mean is here at The Institute of Psychic Development - Psychic Development Courses
... if you do their psi-q test, you get a personalised graphic you can put on your site or blog that links back to psychiccourses... it's taken a few months but they are seeing a nice increase in SERPs
The other variation might be to sell the right to use it in this way to other people... say I'm a charity with a major fundraising deadline... as part of my viral marketing I could get my subscribers to place my ticker with a link back on their sites/blogs... you could charge a small licence fee to anyone who wanted to use it in this way?
Just some ideas...
In light and love
