I came across a neat application the other day that is designed to make file sharing easier. The Dropbox application allows 'easy' sharing between computers and users, even if the computers are running different operating systems.
Essentially the program designates a folder on your computer as a dropbox, and copies the contents of that folder to a web-accessible account and to any other computers connected to that account. The option of having the files accessible online without accessing one of the computers connected to your dropbox is kind of neat, as it allows the accessibility of accessing your files from any computer in addition to those specified as part of your dropbox group. You also have the option of making your dropbox contents available to the public and completely open access.
If nothing else this application could make sharing files from a work computer to a home computer a bit easier. It also has the potential to be useful to those working on collaborative or group projects, and be a lot more efficient then constantly sending out mass group emails.
