Can you attach to a new webservice after runtime?

[Jason Mondanaro]

I have a situation where I am testing the security and delegation of a
dashboard machine to various web services. So I have a client machine with
IE6 that surfs to a page on the Test Server and the asp.net app on the
server calls several webservices machines to make sure that the user is
delegated to each serving application. Now the problem I am having is that I
don't know what all the webservices are that may be developed and need to be
tested. So I was wondering if there is a way to allow a user to enter in a
URI to an asmx page and then invoke a method on the user-added webservice.
Basically the user adds to two text fields something like
http://somemachine/NewService.asmx, HelloWorld, and hits the add button. The
Add button adds a new button control to the page that will invoke the
HelloWorld() method for the NewService.

Is this possible with Webservices and asp.net? Or do you always have to have
compiled in a proxy class to your application?
