If you can, get your licenses setup to key off of the user name,
the machine (host) name, and the display name. Then setup your
serf nodes to all have the same name (i.e. serfxx). The master
node can still maintain a separate name for each node (i.e. serf01,
serf02, ...). When you fire up the cluster, the user/host/display
names for the serf nodes will all be the same and will only require
one license. Thus, two licenses will be required, one for the
master node and one for the serf nodes.

In effect, this is the same thing as having multiple processors on
the single motherboard, which would be a single user/host/display.
There are now multiple processors on multiple motherboards, with
a single user/host/display name.

regards,

Mike
