Fine Homebuilding #128, p. 58. shows a drywall vacuum sanding system. Who makes the sanding unit?…from where can they be purchased? I’m assuming there are sanding units that can be attached by hose to a standard shop-vacs (as shown in article). In my first home-drywall project I used “wet-sanding,” but I was not at all satisfied with the results. I would like to try dry sanding, but don’t want to breath the dust.

I know that Porter Cable makes one, the model 7800.
Haven't used it, just happened to see it in their new catalog the other day. You might check their web site or pick up a catalog at any Lowe's or Home Depot.
*HD sells one, I got the small version for some touch-up in an occupied home. It did work, but couldn't handle the full draw from the Shop-Vac, and the vacuum did still get a fair amount of dust. It works by propelling the air coming from the sanding pad into a bucket of water; I guess the drywall particles are carried by momentum into the water and trapped. I think I could build my own for less money and better performance with some hose and tight-lidded buckets -- maybe 2-stage. It does seem like a pretty good idea.
*Mike,Porter Cable makes a drywall sander that attaches to a shop vacuum, as long as you have a good, CLEAN, filter it works well. We use ours in restaurants and performs well. You will still end up hand sanding with a pole sander in some areas (inside corners, etc.) because the PC unit is 8" dia.You can buy the Porter Cable unit from W.W. Grainger, it's also available in some of the mail order catalogs. You may also be able to rent one, however, I never was able to find one in the rental yards.Good Luck!
*I've tried the Porter-Cable sander. I was not impressed, and ended up returning it. I could not apply enough pressure where I wanted it. A pole sander works much better, and is one hell of a lot lighter.
