My understanding, from the comments indirectly posted from Lahey "The 
license allows
two users to simultaneously develop programs for use on clusters of up to 64
CPUs in size.  The code that is developed can be distributed to an UNLIMITED
number of clusters ranging in size from 5 to 64 CPUs.  The clusters running
the executable code do not need a Lahey compiler, nor do they pay any fees
to Lahey."

So the 'value' they add is the same as for any commercial compiler - the 
environment, usability, speed etc.  The license allows you to *develop* on 
a cluster of a certain size, but the resulting program can be distributed 
ad infinitum, on clusters up to the size allowed for development for the 
cluster, without the need to purchase a Lahey license.
