yes

i don't think so, since you have to "limit" each CPU license in a cluster with
/include=machinename and all cluster machines share the same license database.
so you would need one CPU license per machine.

i still haven't gotten my card, so when i need anything i call and get my
number, and then write it down on a scrap of paper and use it.  i then proceed
to lose it a week or two later, and then the next time i need a CPU license
generated i call up DECUS and get my number again.  my theory is they will get
tired of taking my calls and send me a damn card one of these times (i ask to
get one sent to me every time i call)
