We had a bit of a discussion not too long ago about the general topic.
You can search in the list archive for "How to deploy seamless script
updates to your clients"

You've left a situation that isn't really very flexible since you say
you don't want to copy the agent again.  Nonetheless, I'll point you to
a little bit of fiddling I did on this topic that you could just chew on
and see if it makes any sense.  It's not really "newbie" code.  The
basic idea is that you have a known location which contains a file with
information about available releases; the module has a function a
participating script can call to find out if it has a new version
available.

The rest of the discussion has some other good ideas in it too (a
version control server may be able to provide a kind of solution).
