Dan,

You need to do a little more reading on web services. Principally they are
based on a get request process over http, but if you want a two way process
you could resort to .NET remoting.

ideally - stick with your clients making requests to a central web service
and keep things easy for yourself - and buy a book on web services, it'll be
a worthwhile investment if your gonna be working with them.
