webservice architecture help

I need help with the architecture developing mywebservice. I want a webservice where the clients can send data to each other. How will the architecture look like? Is that possilble?
Like you have a webservice where clients connect. And a client can connect to the webservice and send text to another client. without having each client polling if some data are for them? This is like a service client applikation but with a webservice in the middle =)
Why I wan′t the webservice in the middle and everybody to be clients is becouse I don′t wan′t the clients to run IIS (webserver) and so on, just a clean win form application.

Like a webservice chat, but I hav′nt seen any examples of these. All clients connect to a webservice and get their messages in realtime (asynchronously). Any examples?

How to combine .net remoting and webservices. I want a webservice to connect many .net remoting instances and with the webservice interface you can contorl the .net remoting applikations..
hopefull for answers.
best regards fredrik

I would recommend using WSE for this purpose , especially the ability to do SOAP over TCP. the server could only act as the meeting place. once every client register the IP address, you can use the Routing feature to do direct call to each other
there are few links. there's also an article in MSDN about building a scissor, rock and paper game using WSE, bu i can't find it.
