Enterprise Portals

True but the best thing about Sharepoint 2002 (or later) is all of its functionality is available as Web services (written in .NET) and pretty easy to use from .NET applications ;). More flexible in case you want to customize it.

I did that, and played with it for a while. It seems nice. I also signed up for the free hosted trial. Right now I'm just having a little sticker shock with the price tag if you want to run it for non-employees (30k+). I'm also wanting to see what else is out there, and not just go with the Microsoft offering without comparing it to others. -James
