Can You Implement Web Virtual Directory In SQL2005 Using ENDPOINT?

In SQL2K you could implement web virtual directory (using IIS) that allowed you to query a stored procedure from any HTTP browser (e.g. IE, Netscape, Opera, ...) from anywhere in the world.

For example:

http://www.mywebsvr.com/WEB_VDN?sql=exec%20Display_Info%20&contenttype=text/html

would return a HTML page of information as defined in Display_Info stored procedure. This was very useful but a little slow due to IIS overhead!

ENDPOINT & http.sys allow access SQL2005 without IIS which should be faster (?). Hence I have been trying to configure ENDPOINT to do something similar without success. Furthermore there is little information on what you can do with the "FOR TSQL" option and how to use it.

PS I don't want to use SOAP as the client will be a web browser not an apps.
