Yes, but that doesn't work securely for configs that are shared among
users on a computer without a lot of work that Tunnelblick does
automatically for the files under its protection.

This is getting off of the OpenVPN topic and into Tunnelblick, but:

Sorry, I wasn't clear about how I would implement it: as a ".tblk
without a configuration file" (which currently is treated as an
error).

For example, "foo.tblk" containing only a "user123.key" would replace
the file "user123.key" in the "foo" configuration. Somebody -- in your
case, whoever makes the download-- makes the download be a foo.tblk (a
folder named "foo.tblk" containing a single file "user123.key").

The user just downloads it and double-clicks it. (Of course, the user
will download it as a .zip, so he/she would also need to expand it if
their browser doesn't do that for them.)

The files would only be replaced if they existed in the configuration
already, and only if they were referred to in the config file on an
option on a whitelist.

That's a much bigger change. It's on my long-term list.
