Drop.io is an online tool to store and share anything (pictures, video, audio, docs, etc) privately, without accounts, personal registration, or email addresses. You can also store & access the stored data very simply in multiple ways. You can use an internet browser, you can email, you can send a simple mms or you can even store & access the files through phone or fax.
Drop.io also works like a social network, except that the network will be created by you. It gives you complete control on what to share & who to share with. The free account will let you store & exchange 100 MB of data.
