Where can I find Folder Syncing to a Web Server a la Dropbox?

Question

I saw this somewhere, but I can't remember where.

Where can I find, for Mac OS X, a system that automatically syncs a folder to your web server, sort of like Dropbox does? The idea being that I can edit code on my computer, and it automatically updates it on the server.

It seems so simple, but I can't for the life of me find the service.

Thanks!

Answer 1

rsync seems to do what you want.

Answer 2

Dropbox's web interface IS a web server. But I presume you mean your own server.

So put dropbox on your own server, and have the server serve the dropbox files.
