rereading previous posts it seems I overlooked this argument I've failed to notice since I thought we're talking headless compute nodes.

So just out of curiosity.
Tony are you really implying an X server / client in the SSI nodes ? Aside from the unnecessary cost this would cause major problems as all GPU's should be of the same brand. Considering you'd only install the client X libraries on the nodes and use a remote X > XDMCP ( the machine which renders the image on screen / has display is the X server ) then still it's nearly impossible since kerrighed doesn't support LVS ( common cluster IP address ) that the X client could use to communicate with a standalone X server > could be handy for a multiseat system .
I have some experience with OpenGL clusters, and that is a completely different topic in all aspects ( would be nice though ).....
In any case, the easiest way to implement a GUI is a web-based one tied to a job scheduler.

in all aspects ... kerrighed being part of the kernel instead of a module, changes things drastically....

Kerrighed has a very good, very honest and very transparent business model. Use / share / modify the software any way you like .. if you get stuck, paid support and development is available.

You will always have those who are a little over-sensitive to this kind of arrangement. For instance, someone might ask for help to implement thread migration and get a reply that they'll be better off hiring Kerlabs (which they would be). Then, the person will start screaming 'baitware' or worse.
I feel I need to clarify my statement on this.
The amount of money involved to develop thread migration ( the estimate I got from Kerlabs ) is considerable ( for a person ) and enough to buy myself a nice house.....
Knowing that its very hard to turn OSS into something commercial / proprietary, one could only try to commercialize a web-based front-end / scheduler....

I doubt an ubuntu MOTU will be interested/has time so yes PPA is a valid option...
