There is an early version (un-documented) of PIM-SM (that uses shared 
trees) under the tcl/pim directory. 
This represents a detailed simulation of the protocol.

A centralized version of the shared tree protocol was also included in NS 
release (Polly owns that part... and she may be able to clarify it for you).

Also, I think there's some outside effort to implement CBT in the NS 
framework... but not sure how far such effort has gone..
[maybe the responsible people will respond to this]
