That would be great if you would like to try and implement that, I'm not really wild about the websnapr thing myself, it was easy to do but if you go beyond 100,000 impressions they want to charge for it. It would be much better to be able to do it without the service.
You should be able to work with the mojoportal source code using VS Express 2008 SP1. It sounds like you have the pre-compiled deployment files rather than the source code, you should download the source code to get the full VS solution.
You can send me any modified or new files at joe dot audette at g mail dotcom
If all else fails this looks pretty trivial to integrate so I could do it myself.
