Remoting from Web Services, ASP.Net 2.0

[T*R*Z]

I'm trying to get remoting FROM a web service call to work and it's driving
me nuts.

[assembly:AllowPartiallyTrustedCallers]

....

[WebMethod]
public string RemotingTest()
{
try
{
BinaryServerFormatterSinkProvider serverProvider = new
BinaryServerFormatterSinkProvider();
}
catch (Exception ex)
{
return ex.ToString();
}
return "Okay";
}

Machine.config allows trust override settings.
Web.confg (system.web section) contains:
<trust level="Full"/>

Any ideas how I can get remoting to work in ASP.Net 2.0?
