Introducing new devices that are intended to trust that big, bad, easily
spoofable internet using non-secured protocols such as tftp in order to
get their configuration from a non-local server shows a degree of trust
not seen since the Famous Five, the BabySitters Club and pre '96 O'Reilly
books on writing internet protocols.

Unfortunately, TFTP is the only protocol that many phone vendors
implement -- and VoIP operators aren't happy about it.  Some vendors have
started implementing HTTP(S), but it's far from common at this point.

Odd, we have over 100 different user agents on our network today and I
would say that most of the devices we are working with today support
someting other then tftp.
