There are two (probably a few more) guys in the SharePoint community that do interesting stuff with SP web services, @jvossers and @sympmarc. They both work on Javascript solutions (JQuery) to make things happen inside a site(collection).

Jaap has released his LiveListData stuff and I think it is awesome. Very usable in solutions where you need to have a dashboard that shows the latest live data from updated lists, I actually think this could be something for TunnelPoint. Jaap showed it to me in Vegas and it worked very smooth.

Marc is focusing on a jQuery library for SharePoint Web Services and he tries to make it easier for (Javascript) developers to call the SP web services (correct me if I'm wrong Marc).

The solutions they provide make me think how we can use this stuff inside TunnelPoint and ProduShare, any thoughts?
