I have no idea. But as I said elsewhere, I'm not in any sense a party
to the process that would attempt to define such enforcement matters.

True, but then have you ever used proprietary software with those
irritating floating licences or with licence keys? Sure, a company
doing stuff on the cheap could buy fewer licences than they need - I've
been in a situation where an employer has bought n licences of some
flashy-but-not-exactly-necessary solution that everyone (n + x people)
has been forced to use, and you end up with all sorts of management
workarounds ("if you're not using product X, can you log off and log
back in later?") - and I'd imagine that where technical measures aren't
the means of limiting the number of users, you get all sorts of
management workarounds to give the impression that only one developer
is using the software in other enforcement regimes: having one person
that collates and forwards support requests, for example. That
businesses would rather waste their employees' time at a much higher
cost than just forking out for more software isn't a surprise to me

I believe so, yes. However, the problem with any licensing system is
generally the developer's: if you want to sell a solution based on
Microsoft Office, is it Microsoft's problem that they chose an
ultra-proprietary licence? As a developer you do get to choose other
solutions, however. (Perhaps I've misinterpreted what you meant,

I have no idea. It's best to ask them that question rather than random
newsgroup contributors, I think. ;-)
