You want to transfer a file to a friend, but IM transfer has failed, it's too big for email or somebody is behind a firewall. Head over to Dushare where you can transfer peer-to-peer via browser, as fast as you can upload.
Dushare makes it dead simple to take a file on your computer and share it with a friend. Visit the site, pick your file, decide if you want to password-protect the download, and then share the short URL with your friend. If they can visit a website and download a file, they can grab the file you're sharing. Dushare also includes a chat function so you can talk to the person you're transferring the file to while the transfer is in progress.
Dushare is a free service and requires no registration. Have a favourite tool for transferring files to your friends? Let's hear about it in the comments. Thanks gizread!
