"I doubt both of these statements about HTTP are true any longer."

[BA] In fact, they haven't been true for quite a while. 

Every day users participate in interactive sessions over
HTTP, largely in circumstances where use of UDP media is
not possible.  Because of the prevalence of highly restrictive
enterprise firewalls that do not permit passing of UDP,
the ability to support realtime communications
over HTTP is now considered a practical requirement for 
business-oriented services, such as web conferencing. 

Although realtime communications over HTTP is largely used
as a fallback, measurements show surprisingly high 
audio quality in the majority of sessions, probably because
many sessions take place over well-provisioned enterprise
networks.
