Hi, a customer of mine needs to add ZEN services to a couple additional
servers, but cannot seem to locate the license number that was used to
initially install ZEN on their primary server.

Is there a command or option somewhere that will display the license number
(zenver doesn't, for example)?

Or, will a secondary ZEN install even require a license number? Since the
product has already been licensed, would anything really expire after 90 days?

Thanks, folks
