Intraweb as windows service

[davenovo]

In my understanding, when IIS listens to port 80, it somehow takes exclusive control of that port, so other applications will not get http requests to that port. So if You have IIS on port 80, you cannot have anything else on that computer listening to port 80. Does the Intraweb service behave the same way, or does the Intraweb service allow other applications to listen and respond on port 80?
