I answer-The problem isn't the brakes but the fork crown and rear brake
bridge
along with the chainstays that will limit the size of tire.
See if you have a LBS that will give tires of different widths a try to
find
out.
Lastly, no, standard road rims can accept wide, like up to 32mm, tires.

Like Peter said, I think you'll find the limiting factor on tire width will
be somewhere else on the bike -- not the brakes. I have a Trek 5500 frame
and I tried to mount a set of cross tires (can't remember what size, but
they were pretty small for "cross" tires). The rear tire rubbed the inside
of the chainstays just behind the bottom bracket. I switched the wheels to
a K2 frame that offered more clearance for the rear wheel and the front
wheel rubbed at the front fork crown.
The reason cross bikes use different brakes (typically center pull or, more
recently, disc) is for more braking power in wet/muddy conditions, not tire
clearance.
