While it is great, I am not sure if folks realize the amount of work required to get the above up and running and then to maintain it. So I was wondering if perhaps at this year's LSFMM if we can have a lightning talk or BoF to review just that and give people clarity about the effort required to do get this going and maintaining it. Its clear not only CXL folks would be interested, but also filesystems and likely block layer folks. Would you be up to help review that with folks with a lightning talk or BoF session? Would there be anyone else who can talk about that? Luis
