I use the version number in the file name. I have a self-updating app
with about 20 substacks. When I change one, I upload it with a file
name like "efTimers204.rev.gz". The app logs in and sees that this is
version 2.04. It checks a custom property of it's current
"efTimers.rev" stack and if it is less than 2.04, it downloads the new
one, uncompresses and installs it.

HTH,
