Just came across this, pretty cool. It appears Bakins has started a movement, I too have consulted with him but my build is a little more simplistic than what you have in mind. Here is my general concept:

I have a water line coming from my tankless water heater (Thank you Mr. President for the tax credit and sparge source! haha) that will deliver up to 180F water... the bottle neck is I have Chloramine treated water so I can only fill the pot up at a rate of .5 gal/min (max rate of the filter), I was going to use a fry basket from Bayou and line it with SS mesh as well but after consulting with GreenMonti decided a solid walled pot with a perfed bottom would work just as well but allow for sparging should I elect to go that route.
So I got a 75L, 316SS pot off eBay for $70:

Started drilling 1/16" holes, 5/32" on center.... this is going to take forever but should provide some advantages over larger diameter holes:

Took off the handles and got some eyes welded on so I can hook this up to my pulley and hoist this pot out:

Got my stand put togther, just need to mount the burner and paint it with POR-20:

And besides only using 1.5 pots what I like the best is the small footprint, 20.25x20.25x25 (45" with the 100qt main pot resting on the stand).
Just waiting on my main pot to ship out from the factory to GreenMonti to work his magic on a 1" coupler for me and it should be on!
Similar idea, just not as fancy as what you are thinking of.
-BTW, sorry Wortmonger for stealing the pic of your coated keggle, that thing is just plain awesome-
