Anyway not all laptops auto distort 800x600 do they? Some do the black lines instead.
If Laptops are setup like normal PCs, odds are very good that it's all configurable in the vid card drivers.
Anyways, regarding widescreen support, I don't see the hassle personally, you just need to code your cameras and GUI to work and re-position themselves correctly on different setups, similar to CSS coding.
