Just to formally close out the carpet thread, there appears to be a single
source for the stuff.  3M makes tiles and treatments, and many carpet
companies have carpet that has a special anti-static backing, but only one
seems to have "certified" static-free carpet.  

You can find it at http://www.utp.com. The process involves some
type of conductive carbon fiber woven into it that is bound to a
conductive backing.  At approx. every 1000 sq. feet there is a grounding
strap.  The carpet is available in rolls or in tile-sized pieces, and
looks to be completely safe for any computing environment.  Pricing starts
at about $22/sq yd. for the roll product.  Any carpet installer should be
able to order it and install it, as there is no special process involved
other than attaching the grounding strap, and anyone who's handy should be
able to figure that part out.  The folks at UTP are pretty friendly on the
phone and will answer any technical questions you can think of.  You get
some nice free samples if you call.

We're going with this solution.  Our machine room is very small, and the
surrounding build/test/repair/work area isn't that much larger and could
use some static reduction.
