gradient selection tool

Hi folks,

I have this idea for a more usefull selection tool: a gradient selection tool. I even have an idea about the algorithm:

0) a seed pixel is selected 1) do a feather selection (magic wand) | RGB(pixel)-RGB(seed) | < treshold 2) calculate a (linear) gradient that fits the selected pixels the best 3) now do a new selection
| RGB(pixel)-RGB(gradient(pixel)) | < treshold

I've looked at the sources the feather select tool, but I do not see an easy way to implement this myself... any seasoned gimpers that could implement this quickly?

of course, typical variations could be RGB-> R or G or B or H or S or V ...
