Say Hi to JustBeamIt, a hassle-free P2P file transfer service that doesn't require sign-up. JustBeamIt lets you upload a file and provides you a private link that you could share with anyone you want. All you need to do is, drag the file you want to share and drop it anywhere on the JustBeamIt webpage in your browser. Once you upload the file you'll get a private link that could be used once only and you'll see a "waiting" indicator, meaning it is waiting for the recipient to download the file. Share that link with person you want to share file(s) with, you could even see the progress once transfer begins.
It is very pivotal that you keep the browser window open until the download completes on the recipients end otherwise you won't be able to transfer. Once the download is complete and both sender and recipient leave the page, the link to the file will become useless. It supports file up to 2 GigaBtyes.
