Kyle,

Inner worlds will not have their own canvas. They will be drawn instead on the canvas provided by the World of which they are part, just like any other morph. It is only the outer World that has an explicit canvas. If you are interested in experimenting in this area, I would suggest writing (carefully!) a #fullDrawOn: method for PasteUpMorph that

- if it is not the outer World 
- and if it has a worldState with a remoteServer then

use a MultiCanvas as a substitute for the supplied canvas when you send super fullDrawOn:.

Cheers,
Bob
