Request for pause/resume sync

While trying to maintain a couple of databases and frequently-accessed files, and a GitHub repository, on Dropbox, I have pretty consistently found occasional, hard-to-diagnose, impossible to replicate errors that I think are caused by Dropbox and other programs fighting over access to files -- generally files that you would expect the program to want exclusive access to while active.

For me, all those problems completely vanished when I made it a practice to always pause sync before running any program that wants access to Dropbox files while running. Except, of course, when I forgot to.

So If I am going to host any working directories on Dropbox, as I now do, I would like a function I could set up to automatically pause sync before R opens any directory on dropbox, and then resume on exit.

Would that be an appropriate addition to your package?

Start by reviewing rdrop2's Dropbox integration and any existing access or sync-related entry points; the issue names no files or tests. Determine whether the package can support pausing sync before an R program opens a Dropbox-hosted working directory and resuming it on exit, then define the supported scope and completion criteria.
