Don't have to post as anonymous.

It's pretty interesting though, ATT cell tower serving Annapolis and surrounding areas is totally dead.  Bummer for us 
new iPhone users.

Regards,
Phil

About 10 years ago, when I was at Precept Software deploying our product
IP/TV, I implemented the RSVP protocol to carry IntServ requests to a
peer implementation being done at Cisco.  It wasn't among the easiest of
tasks.  I can't remember the details apart from the need to process
floating point numbers in an integer-only environment.

But there is something more important than the technology: A lot of
"southern" countries are using or considering VoIP for their telephone
structures.  Yet they face a serious concern: How can they feel safe in
their investment if they can not obtain assurances (I avoid the word
"guarantees") of adequate levels of service so that their cross-border
phone services will be usable?

It strikes me that one of the needed bodies of internet governance is
some sort of clearinghouse arrangement through which potential consumers
(or more likely, their ISP's acting as agents) can obtain end-to-end
assurances of service levels.  (My mental model is sort of like Lloyds
coffee house in London where people who wanted to underwrite shipping
insurance would congregate.)

How such assurances (again, not guarantees) might be mechanized would, I
imagine, be through some combination of path and routing engineering
coupled with ingress constraints to reduce the chances of edge overload.

Of course, I do expect that people would have to hand over $$ (or more
likely Euros) for this kind of thing.

But I would also expect that it should and must be free from
manipulation and unfair self-dealing on the part of the providers.
