Senduit – Free File Sharing Service
http://www.senduit.com/

Senduit’s service provides users with the ability to upload a file via HTTP-Protocol and receive a custom URL address to download the file from Senduit’s servers. This address can be shared by the user freely and can be used to download the file a reasonable number of times. The address expires in an amount of time designated by the user (between 30 minutes and 1 week) at which point in becomes inaccessible to the public and is removed from Senduit’s servers. This has been added to the tools section of Research Resources Subject Tracer™ Information Blog.
