Linux already has RDMA support but it cannot yet use Thunderbolt. It's probably quite a bit of work to add everything that's required. Is anyone working on it?

It would be great to have this for those cheap Strix Halo boxes with 128GB quad channel DDR5-8000 for using two or three of them with their 2 USB4 ports (which are Thunderbolt capable) to fit larger models.
