I've never used Orange, but one thing you could try is casting 
your object from MyInterface to Object, and registering the type 
Foobar like in 
http://dsource.org/projects/orange/wiki/Tutorials/SerializeBase, 
then serializing/deserializing it as Object rather than 
MyInterface. I'm not sure if this will work, but it's worth a try 
if it doesn't handle interfaces. Interfaces are a bit odd in some 
ways, as they are not necessarily classes (and thus not 
implicitly convertible to Object) in situations like with COM / 
extern(C++).
