Multiple users on one machine and Dropbox

If UserA logs in to an OS X machine (at the GUI) and starts Dropbox, UserB logs in via ssh and adds a file to their Dropbox, will Dropbox work for UserB? Or does UserB need to log in via the GUI also, and then "switch" (not log out) to UserA?

Solution 1:

DropBox does not support not-logged-in users. The solution seems to be the following:

Log in and start Dropbox from the command line:

alias dropbox='/Applications/Dropbox.app/Contents/MacOS/Dropbox &'
dropbox # start it.

ps aux | grep -i dropbox # shows multiple instances running

The above technique seems to work. Error messages are sent when the second Dropbox launches:

already someone listening at socket

RegisterApplication(), FAILED TO establish the default connection to the WindowServer, _CGSDefaultConnection() is NULL.

But everything appears to work.
