Startup Idea : Anonymous One Click File Hosting

So I have an Idea that I kind of like. I would like to run it by ideaswatch before I go too far on it to realize its gonna fail. Basically I want to make a website that allows you to one click upload. You don't have to register or signup. There will be a button on the top of the page that says 'upload'. When the user uploads a file (max size not determined just yet), they are redirected to the page the file sits on. Also it gives them a password that they can use later or now to change details (They can change password to fit their needs), description, filename of the file. To prevent spamming and stuff I also thought of adding in a time limit for files. The user can extend this time, (Needs password). Another feature of this site would be that the files are broadcast (if made public in the settings), but by default are private and only viewable by going to the specified link. If a public file recieves a good amount of attention, the file's time limit will be extended. At any time the user can take down the file. Also others can report files. Ideas? Comments? I would like feedback on whether to pursue this idea or not. Please and thanks.
