I've seen info on ordering a phone line transformer that will give you a limited amount of 110 without interferring with the phone service. It claims to be able to put out enough power to light a 100 watt lightbulb. Anyone ever hear of this, or better yet, have a schematic?

A phone line is designed to power a telephone. The power that a phone uses is about 10V at about 20mA which is only 0.2W of DC. A transformer needs AC, not DC and if the voltage is stepped up then the current is stepped down so that the input and output powers are the same.
You won't get 100W and you won't get 110V.

You said "a limited amount of 110". Maybe you could use the phone line to slowly charge a capacitor that can power an inverter for a moment. The duration of a flash from a 100W light bulb would be so short that you won't see it.
