Dynamic objects?

Not sure if "Dynamic Objects" is the correct title for this, but here is what I'm trying to accomplish.

I'm trying to build something similar to how .NET can create a strongly typed object reference to a remote web service.

On the client, the user will use my custom object. That object will somehow need to query a remote server via some transport (www, tcp, etc), and get the latest schema in order to build it's strongly type reference to a particular object.

Any help and/or pointers in getting started with something like this would be appreciated.

It has been a little while since I have dealt with this, but WCF services allow you to publish types. This would not be at runtime, though. When you discover the service, all the datatypes in the contract are then available to use.

I'm staying as far away from WCF as possible. I really want to do this with pre 3.0 technologies.

Maybe I should be more clear. I'm essentially trying to create my own .NET Remoting mechanism without using .NET remoting. I'm trying to more understand how to update the data contract on the client to match that of some remote schema at design time. Is this really that hard?
