Why?
If it were an open-source project, yeah "why not" is a fine answer.
If you saw my face when I saw the OS/2 bootup screen on a ATM that just rebooted when I was in front of it...
For your point though, most probably it wouldn't be the ATM that does it. The ATM would send/queue a notification to some other resource in the bank network, for that to do the whole email notification piece. But that should be possible today (or even years ago).
Reminds me of those people using `resource' as a synonym for `warm body'..
(You are absolutely right in your intended meaning, though.)
