	I think that was one of the options that Glenn suggested.

	I can confirm that it works, as we do something similar here at UCD.
	We have behind-the-scenes magic like yours, but using Perl rather than
	Ruby, which generates new dhcpd.conf files as required.

	I expect you'll need to be aware that mixing "allow" and "deny" can
	lead to confusion.  I've chosen to use "deny" in all cases: where I 
	want only known hosts, I use "deny unknown" and conversely.

	I hope this helps.
