Convert from V-brake to Cantilever?

I have a Specialized Sirrus that at one time had been converted to a drop bar road bike. Since the frame is set up with V-brakes, I used a device called travel agents to accomodate the 105 brifters. After getting a new road frame, I moved the groupset and the handlebars over and am once again left with a frame and fork which I intend to build up again. This time I was thinking of using cantilever brakes instead of the travel agent/road brake setup. I plan to basically set it up like a cyclocross bike. Does anyone know if the cantilevers fit on a frame originally set up with v brakes?

They'll use the same bosses. That said, do you have provisions to deal with the fact that the cable pull needs to come from the center? Since most V-Brakes come in from the side and use a noodle to cross over that may be something you'll have to adapt.

"Problem Solvers" makes the one for the front, replaces a headtube spacer. For the rear you'll probably have to use one that comes off the seat post if your frame has no provisions.

Right - like CCrew says - the arms for the cantis will fit on the bosses just like the arms for the v-brakes, and you will need some type of cable hanger above each of the brakes. Here's one for the front similar to the Problem Solver CCrew references, but made by Tektro:

For the rear, bikes that are built to take cantis usually have a bridge across the seatstays that serves as the hanger. If you don't have this bridge, you can get one that hangs off the seatpost binder bolt like these, or Surly makes a nice long one:
