So thunderbolt is PCI-E at the end of a cable, Cool.
I can see people building neat, cheapo numa boxes with this.
Think sgi altix on the cheap.
For those that don't know, the SGI Altix has a special chip that intercepts memory accesses and maps other systems memory to be seen as "local" on each system. If thunderbolt is just pci-e on a wire, you may be able to connect a few systems together and just map memory across systems. It'd take some trickery, and wouldn't be quite as fast as infiniband, but the thought of building a ghetto supercomputer would be useful to many people.
