I can't imagine the effort involved in hardening all applications to
treat the hostname as untrusted input.

ISPs that sell vservers are really no different from Intel or AMD or
whoever makes your CPU -- you trust them completely and totally with
your data, your executables, and your entire operating environment. They
can inject anything they wish into your system's memory whenever they
wish.

Making sure the dhcp clients don't allow setting these kinds of
hostnames however, that might be a good idea. Enforcing the usual dns
guidelines of a-zA-Z0-9-_ might be worthwhile..

Thanks
