[atlas] Encouraging people to upgrade software probe versions

Hi,

I recently posted two threads ultimately related to the same question,
where it turned out that a feature I wanted to use was present in the
current software probe release, but not in the old version that I had
installed.  It was indeed relatively easy to upgrade (as a reply on
this list predicted, the upgrade didn't break anything or require any
reconfiguration).

But I'd still say "relatively easy", because, on the other hand, the
upgrade wasn't managed through my OS package manager like the rest of
the software on my VPS server.

It appears to me that a lot of software probes (like mine was until
recently!) are still running whichever software probe version was
current when they were first deployed.  After all, I don't believe
there's automatic software upgrade functionality in the methods that
most people are using to deploy these.

Is that true from the point of view of the rest of the Atlas community?
Is there anything that might usefully be done to encourage people to
upgrade periodically?  (For example, either sending some kind of e-mail
reminder, or distributing probe software via OS package managers, or
even including a mechanism in the probe client itself by which it could
upgrade itself -- even if as an opt-in feature?)
