[e2e] Skype and congestion collapse.

[Lars-Erik Jonsson (LU/EAB)]

Sure, of course there are good reasons to have communication
means that are more reliable than others. However, it is not
at all obvious that an application for conversational voice
is a good choice if you want to create an emergency solution,
i.e. an "almost always working" solution, as conversational
voice is rather demanding in terms of delay. Remember there
is no way to ensure something will *always* work, it is just
a matter of more and less reliability, and extreme reliability
is costly. 

I party agree with you, but I do not think it is about "an"
emergency solution, but rather to enhance the possibilities
to increase reliability end2end, and thus create a basis for
emergency communications.

But main point being, VoIP can be so much, and in most cases
I believe it is very different from what POTS has been about.
The good thing from a user point of view is that users now
have a chance to choose application based on own preferences,
and not pay for more than is actually desired.
