In what little testing I've done, it looks like, if I have to publish
multiple scripts, I have to do it once for each one. Our development
scripts are structured in a psuedo-object-oriented fashion. It would be
convenient then to take a directory, or a group of files and publish
them to IOS all at once.

But Link is extensible through REBOL, correct? So if REBOL can, I assume
we can create an app in Link to do so.

I mean, within Link, using REBOL, can I intercept a change in a file and
us it to fire of an action. It is functionality that we could use to
help us manage our scripting process.
