I just wanted somewhere to keep images/files that will at least be up as long as SL.

I could definitely see the use in that, i'd use it if you had it just cause it's proprietary to the site

be cool if you could connect SL accounts directly to it, so each user had a library of pictures they posted/uploaded to it

EDIT:
I second @emilia's API suggestion

It would be so cool to create a desktop CLI Sinisterly Linux Client
