Leases based on MAC addresses

[Elliot Finley]

is there any way in the newest version of ISC-DHCP to have MAC based 
leases rather than UID based leases?

If not, is there anyone willing to code this into the official release 
for $$$?

If not, can anyone point me to the right place in the code to hack this 
in myself?

Thanks,
Elliot
