Heh. I wonder if someone could code up a PAM module that would make a tiny BitCoin donation every time a remote ssh login was performed. Like, a voluntary thing that people could install to support the project.
Oh yes, please make my logins traceable for all eternity....
logistically that's unworkable for a number of reasons (bitcoin fees make micro payments...less useful; PAM is...not ideal; etc.) but a fine thought nonetheless.
It could just count the number of logins and do a transaction at the end of the day|week|month
You could have it accumulate a wallet and send over when it reaches sufficient magnitude. Or have it tally the number of times it would have done it, and then ping you when you've used it a sufficient amount, for whatever definition that is for you. Think Sublime Text save dialogs for the non-paid version.
There's no PAM on OpenBSD.
Indeed, BSD Auth serves a similar function on OpenBSD, except for the ability to make silly configuration mistakes.
