	I have one firewall running pfSense.  It stands guard between my

	box has two NIC's and the mail/web/DNS has only one, but that's
	how my LAN guy reconfigured things.

	one thing I'm thinking of is to get One fast and lower-power server,
	having two jails.  One jail would be as-is with mail/web/DNS and the
	other jail would be "tao", my main server for years.  When I buy
	a reasonably fast ThinkPad, it could run Ubuntu and I could
	reconfigure my older boxen for emergencies.

	They are finally waking up!  Especially as their own costs
	skyrocket, and as the poor consumers {that's us} start yelping as
	our power bills hit the ceiling.  It will be at least a few years
	though, so for now, yes, it's our responsibility.

	And of course these costs are passed along.  Borne by not only
	the consumer but by the planet.  ....

	The way I see it, since we {us-[BSD]-geeks} are among the most
	savvy folk on the planet, it's make sense for us to be in the
	lead on this type of issue.  [volumes left unsaid]


	PS:  just spent 20 minutes crawling around beneath desk.  my
	bare-bones ubuntu draws between 100 -- 107w.  isling.
