We've been curious about FhGFS but the licensing did not leave us confident
we would always have access to it if we integrated it into our business and
made available to our users.  Serious success could essentially cause an
epic failure if the license made it expensive to us (as commercial users)
suddenly.  As a "cloud" based hpc provider I thought it was too risky and
have been happy with Lustre and it's affiliates.

Specifically this clause could be a problem:



- rent or lease the LICENSED SOFTWARE and DOCUMENTATION to any third party


Does anyone think the license was intended to block cloud providers
making it available as part of a cloud based HPC solution?  Am I
mis-interpreting this?  Not looking for a legal-ese battle but I am
wondering if other licenses commonly used in cloud contexts have
similar language.  Anyone think the FS is fantastic enough that I
should fight (spend money on lawyers and licenses) to put it in front
of "Cloud" HPC users?
