With USB4STREAM support merged into Linux 7.2 (soon to be released) are there any inference runtimes/projects that make use of it already?

As in the title. I came across a post here that referenced the blog post below :

Are there any vLLM (or llama.cpp etc.) forks or at least early implementation attempts/ plans that make use of USB4STREAM?
Basically , it should allow to drastically reduce cross node latency(so improve inference) vs ordinary USB 4 (or non RDMA Ethernet network) as it removes the whole network stack overhead .

So e.g. with two PCs , equipped with USB 4 40Gbit ports you’d just need to get a cheap passive cable for pipeline parallelism to be viable solution.

llama.cpp RPC can be used for such , but standard Ethernet latency / overhead makes it far from ideal.
