[Twisted-Python] restricting twisted web to a single connection

[Don Hiatt]

Hello,

I'm just getting started with twisted and have a question
about twisted web. How would I go about limiting the web
server to accepting a single connection? I know you might
be asking your self why anyone would want to do such a 
stupid thing, but I'm controlling some hardware and need
to restrict access to it to a single user at a time.

Anyway, I'd appreciate any pointers. :-)

Cheers,

don
