Absolutely.  The Servlet API is sufficiently generic to allow you to write
servlets that implement RTSP without having to implement HTTP.  The
difference
is between the generic Servlet API (javax.servlet) and the HTTP-specific
classes
(javax.servlet.http).  Gary, you would be extending the implementation of
javax.servlet, not javax.servlet.http in your RTSP classes.  Servlets are
most
definitely not an HTTP-specific technology.

Actually, a servlet can do anyhting that the host environment will allow.
I've seen a servlet that does one task, but serves up multiple interfaces:
HTTP via the standard servlet stuff, *and* a direct open socket, *and* RMI
(CORBA).  The client(s) can choose which interface to use.

The example is in McGraw Hill's "Java Servlets" by Karl Moss.  It's pretty
cool.
