Ultimate Trainer; The One. Could it be done?

[DTJango]

Something I've been wondering about is why no one has made an attempt, at least an open one, at making an ultimate trainer. Yeah, I know, some have the title "Ultimate" or "Mega", but I mean like THE trainer. Or at least a program to access and download trainers in an easy-to-use interface.

Essentially a Steam of trainers where you can go through, download and update with just a couple clicks.

I'm sure it's possible, but do you think it's crossed the minds of any major trainer maker?
