oh is it?   I did a rpm -qi and saw your name and assumed it was from 
rpmforge.

isn't that a canned bind configuration?  ah, yeah, thats what the 
package info file says it is.

bind is a lot more complex than dnsmasq.   dnsmasq uses /etc/resolv.conf 
for forwarded lookups, while a caching bind server either uses
a statically configured forwarder, or a root cache zone, and running a 
root cache zone on a intermittently connected system ('different ISPs') 
isn't a good idea.

dnsmasq will also serve local clients with dns using entries in your 
/etc/hosts file, which can be handy when you have a few static hosts on 
a small masqueraded network.
