Just the other day, I was asked if Geocortex Essentials can work with Sharepoint. To be honest, I don't have the answer - so far, we've primarily used Sharepoint as a CMS and data-integration tool. I can imagine a case for data linking of Sharepoint Lists into Essentials or perhaps some combination of a Web Part filter to pass a value selected on a List to an Essentials Web Part.

I'm curious to hear ideas from people using Geocortex Essentials - how would you like to see it work with Sharepoint?
