Sorry, but I simply don't see it. First off, users already have problems entering something comparatively simple such as w&b data. T/o distance data is much more complicated with many more variables such as flap setting, etc. Just look in POH's section for the t/o distance of a couple of different aircraft. They look vastly different, depend on different variables. If you have two engines, it's again a totally different game.
I did something like this once for the DA20 and it was pretty involved. I had to use flight testing data and do a 2D interpolation on several variables. Definitely not something which I would like to do again for different aircraft. And I doubt that many people would have the tools and know-how to do it for themselves. Heck, a lot of people have troubles getting simple w&b data to work in SD.
And then there is liability as well. I would not want to be in Tim's shoes when someone crashes and burns because the t/o didn't pan out even though SD said it would.
