I do not know if the ab/dl community could be organized enough to do something like this but I for one would pledge my money towards funding a ab/dl diaper company.
the only thing i would ask of them is to try and never exceed the one dollar a diaper model trying to keep all products within that range just wishful thinking really.
Also this guy
I am not sure of what the current population is of the ab/dl community but it being the age of the internet and more people discovering it and involving themselves within the community then I am pretty sure there are plenty of working diaper butts out there that would be willing to fund this sort of thing...
EDIT: I would like to do a test run on the kickstarter say set it for 1million just for laughs and set the pledge at 1 dollar for 1 week to one month just to see how many people there are that are willing to pledge.
