I'm new to using cantilever brakes (or at leas it's been a long time), and I find that in order to disengage the cable to pull a wheel off I need to have them adjusted pretty slack. (35mm tires)
The pull required on the levers is more than I'd like.
Is there such a thing as an inline barrel adjuster akin to the quick release on calipers that I could install?

I have them on a couple of my bikes. They are both on the hangers. Haven't seen an inline one for brakes though.

Empella, Spooky and some of the TRP knockoffs,'eurocross' ,
that are formed somewhat like old Mafacs,
out of 2 pieces of aluminum joined by the bushing and the pad holder , have been modified
to put a barrel adjuster under the head of the transverse cable, because they can.
Oh. and Kool stop makes some brake shoes that come apart
Shoe comes off the post, without changing the adjustment.
If the pull required by the cables is more than you'd like and/or you are unable to release the brake cable without adjustment, then you probably have your brakes set up with too much mechanical advantage. Welcome to the wonderful world of canti adjustment! :D
Higher mechanical advantage gives you more braking power, but it also causes the pads to move less proportional to how far the brake lever moves, so with a lot of mechanical advantage you need to set the brakes up close to the rims. Try raising the yoke a bit.
Oh yeah, knobster is right that cable hangers with barrel adjusters are available, and there are definitely legitimate uses for them. Getting your tires off just off the frame just isn't one of them. :)

I just ordered a pair of Jagwire inline adjusters for my bike. Although my brakes are fine without it, I like the idea of being able to take up the slack during a ride as the pads wear.

Yeah I just put a shift cable inline adjuster in it for my rear and have one mounted on the front hanger.
