The RFC's actually state that a domain MUST start with a letter, and

No! Wrong! Totally wrong! If they were illegal they would never have been
allocated. Duh.
RFC 1123 section 2.1:
The syntax of a legal Internet host name was specified in RFC-952
[DNS:4]. One aspect of host name syntax is hereby changed: the
restriction on the first character is relaxed to allow either a
letter or a digit. Host software MUST support this more liberal
syntax.
Ah, I thought I remembered something along those lines but
couldn't find the reference.
Also, for what it's worth, there are some legitimate businesses
that use domains beginning with a digit. 3Com, for instance.
