[epub] Google style ad serving alternatives.

[Lewis <lewis@xxxxxxxxxx>]

Hello
Does anyone know of any Google style ad serving alternatives?  It seems 
like about 25 to 50% of our ad space in not used up by Google ads.  It 
would be nice to sell that space using a similar model (per click).  
Anyone know of solutions for doing that?
Thanks
Lewis
