Assuming Dropbox is setup properly and all files are set to be “offline” (IMPORTANT), you can run DEVONthink on two machine simultaneously. The two machines hold independent copies of their own databases.
DEVONthink will launch Dropbox per how you set it up (manually, automatically, or at set intervals). Once the sync puts the files up to Dropbox Server and then down to both machines, the two machines will be in sync. This process is not instantaneous and depends of course on a lot of independent factors like bandwidth, sync schedule, etc. I run in “automatic” and I can look at the “Today” smart group to see the files appear I store on one machine eventually (usually within a minute or so) show up on the other.
I like to think of all this as magic and I don’t try to figure out what that Dropbox sync file is about.
