Before a sip solution can be specified, the requirements must, 
explicitly or implicitly, be interpretted in the context of the sip 
operating environment. Doing this implicitly is to guarantee 
disagreement about the validity of the chosen solution. I don't deny 
that it is work. But it seems to be work that must be done in any case, 
though it otherwise might not be done in IETF. It makes sense to me that 
this work at least be shared with the IETF. Doing that interpretation is 
really work that TISPAN must ultimately do, though people here are 
probably willing to express opinions. Naively, I am inclined to hope 
that this work has already been done, but we just haven't yet seen it.
