Subsuming other network resources under Croquet

Hi there, The web begain with ability to subsume other network resources - such
as usenet groups, gopher lists, and printers - under itself via linking.  Any
such resource could be respresented and accessed via a hyperlink on a webpage. 
This of course accounts in part for the webs enormous reach.  

My question here is, to what extent does Croquet offer the same 'subsumption
power'.    I understand, for example, that I can subsume webpages and internet
resources via Croquet.	But how does that work?

Also, what about other applications?  Can I run other windows or Mac
applications inside a Croquet world on my desktop, and then share that
application in a Crquet world/window with other Croquet users over the
internet?  

Any guidance on these matters would be appreciated.
