For my own development efforts, I use Axosoft's OnTime product which is free for a single user (yeah!).  I have a single SSL for Axosoft and for my WSS Team Site installation, so I needed for both to coexist peacefully in a single virtual server.  Out of the box Axosoft was throwing several errors, at which point I came across this link from Microsoft: 

How to enable an ASP.Net application to run on a SharePoint virtual server

After completing the steps in the article OnTime began working flawlessly!  Nice!
