Something similar to Loopcloud to organize samples?

Recently I saw a teaser Loopcloud and it seemed a fantastic idea. It's online samples library like Splice Sounds, but with workflow speeder plugin. It allows playing samples in sync with DAW, search samples by key/ tempo/genre/tags, shuffle loops, change pitch and repeat beat in MPC style.
But there's a nuance. I thought Loopcloud can tie up with my current sample library but it's "library folder" is allow you only to keep samples you bought in Loopmasters on HDD. It's not useful if you don't have many samples from their libraries.
So is there similar apps to keep sample library organized? And how do you organize your sample library to speed up the workflow? As a lazy person, I'm gonna die to put keys and tempos in every loop file name.
