Looks nice - thank you!
Just an idea: I may put the "dhcp-mac = set:special, ..." lines into a  
special file in the directory defined with "conf-dir". Perhaps with a  
leading "pxe-service = tag:special, ...".

What about defaults, wild cards etc?
My favorite solution is (in pseudo code)

if exists $conf-dir/mac-special-list
  then use special pxe server for these MAC addresses

else
  use normal pxe server

Viele Gruesse!
