First off, thank you to everyone for your input - you all make very good points!
I actually might've found a place in Portland that will build around the Troll frame. They seem to be a comprehensive shop that can probably offer lots of options for both new and used components. I'm looking for an ultra-practical/reliable build, so am absolutely open to getting used parts that are in decent conditions, especially those that aren't immobile and not mechanical (seatpost, handlebars, stem, etc.). I think they might be able to build very close to my ideal for about the same price as the Troll - complete bike:

not true: any "rim brake" rim can be used to build a wheel on a disk hub. Viola: dual purpose rim. Just dont use a rimless "disk rim"
I have both Brake types on various bikes (in addition to centerpulls and sidepulls), they both work just fine. Again: non-issue.

Commute...sure...but I loathe them when they get dirty and squeal and unless you get BB7 or others that can be adjusted on both sides I find them a serious pain to adjust. They are critical for winter use but in my experience that's about it. A tweaked rotor is a huge PITA and not easily straightened without three adjustable wrenches. If you go with disc, I would agree that cable discs are the ONLY option unless your touring is strictly U.S. based where bike shops or supplies can be reached easily since bleeding/refilling is more complex than a simple cable readjustment.
Again, very good points! I'm ambivalent about discs; while I like the idea that they greatly extent the life of rims, I'm partial towards absolute simplicity, esp for touring. I know mechanical discs are pretty simple, but I always remember Murphy's law. I'll definitely discuss it with the shop.
Thanks again!
