[IronPython] remoting from IronPython

Hi again,

I searched a little further and found out the following:

When using remoting - server activated objects:
and s = NameSpace.RemoteObject()
I discovered the "Cannot load type 'clr:IronPython.Runtime.IDynamicObject, 
IronPython...." exception occurs on the following location:
namespace: IronPython.Runtime
file: Ops.cs
funtion: public static DynamicType GetDynamicType(object o) {
Line: if (dt != null) return dt.GetDynamicType(); (line 562)

during debuging I discovered that 'object o' (input of the function) is of 
type MarshalByRefObject so I guess its my remote object. The first line in 
the function is IDynamicObject dt = o as IDynamicObject;. dt is not null 
after executing this line. This is strange because its being casted to 
IDynamicObject, which isn't implemented by my remote object. There after 
when the next line is executed if (dt != null) return dt.GetDynamicType();, 
the exception occurs.
Can anyone tell me why this is going wrong?

I also tried to use client activated objects. In that case the remoting call 
is working correctly.

Thanks for your help again.
