In any event, you'll need to modify PIM itself to propagate your 
information up the shared tree.

Given that there's an RFC published for extending PIM with attributes 
now, it's slightly more likely that vendors will adopt the RFC just 
because it exists -- although that obviously doesn't guarantee that 
anyone will implement the RFC at all.

There is a learning curve for the XORP PIM-SM implementation, and the 
time involved in that learning curve is probably high enough that it is 
worth implementing PIM attributes anyway. You certainly don't have to, 
that is just my opinion -- but be aware that PIM is a difficult protocol 
to extend, for the reasons I gave in my original reply, which is why the 
RFC authors spent time drafting an RFC and putting it through the 
rfc-editor meat grinder.

P.S. Please Cc: questions/messages about XORP to the xorp-users list as 
I cannot respond personally. Thank you.
