@ducks4you, I use my pressure canner on my glass stovetop. Biggest issue is keeping the pressure regulated due to the #$%^ pulsing action of the heat. But no problems with the glass not being able to take the weight.
It depends on the stovetop. You can check with the manufacturer and see what they say about canning on it. With some it's OK, some say don't. The two possible issues are the weight as you mentioned, and will trapping heat down there cause overheating problems to the stove itself.
I have a heating coil Whirlpool and bought a special canning coil for it. It has structural reinforcement and sits up a little higher so the heat can escape from underneath.
