Sorry, I can see in retrospect why that could be confusing. When I said we are a Datatel school, I meant we use Datatel as our SIS. We haven't committed to a portal project yet.
We are going to use Datatel Portal. If you are going to do this, understand that SharePoint is a very large application that eats up lots of resources and time. If you do not have an existing implementation of SharePoint, your research should certainly include taking a close look at SharePoint as a whole.
