Yes. I noticed your e-mail domain :-)

And I see, that there _are_ scenarios where multimedia over IP does make 
sense. However, I don´t see those scenarios in "The Internet".

And I think, it´s the general way to go e.g. for VoIP in company networks.

However, for the general Internet, when I see RSVP and QoS and all these 
things, it´s not only that these apply TDM techniques to the Internet.
It´s the question how "telco like" the Internet shall be?

The more QoS we bring to the Internet the more "telco like" the Internet 
will become - and the more expensive.
