Bill,

Gated does have an option to use DNS names instead of network numbers
but if you use DNS names for everything unless every router is a DNS
secondary, you end up with a chicken and egg problem and routing nver
comes up.  BGP and IDRP are inter-AS protocols.  If an AS changes
their DMZ address, I think it is OK to have to edit a config file.  I
don't expect every Mac and Windoze toy in the office to be running BGP
or IDRP, so this is not an issue.

ps- I suppose you are going to want us to consider the implications of
policy routing with mobile AS numbers next.  :-)
