Is it possible for a msp object I write to create another (existing)

This is not currently supported by the API.

I've hacked some objects together which do this sort of thing, but it 

was only possible because I had the source to those objects and could 

write specific code for the specific interfaces of the internal

I've hacked some objects together which do this sort of thing, but it  
was only possible because I had the source to those objects and could  
write specific code for the specific interfaces of the internal  
objects. It's a very ugly hack.

This has been a point of discussion for the future. For now, it's  
pretty much impossible.

Yes, for a future SDK, this would be very helpful.

create implicit msp object inside another?
