I'll need to write some code somewhere so NFS & NFSD can handle this request. I could keep any implementation internal to NFS / NFSD, but I'd like to find out if local filesystems would find this sort of feature useful and if I should put it in the VFS instead. Well, one actual not very detailed request, and one question from a poster who just asks random questions on the list all the time for no good reason. If you care about it prototype first, check is feasible and see if it gives the expected results. After that you can report back with the findings and have an architectural discussion. But unless that gets stuck you should be easily do that on the list instead of wasting meetings slots on hand wavy stuff.
