i'd love to try to turn a server on every 30s for like 2s then turn it off again. rtcwake could be used for this. dont spin up your platter drives each time though or you might wear em out fast.
the tricky part is that a consumer would have to catch you at just this time. a mdns broadcast being a signal- contact me now- would work, but what apps are going to have that kind of timing built in?
it'd be interesting to see which kinds of protocols would be ok with servers that just keep disappearing. webdav might be fine. smb/cifs would probably throw a fit.
or... ideally the nic could be some kind of smartnic that could stay on & buffer some traffic, keep connections open. i wonder if cxl gear, with multi-host capabilities, might enable this sort of thing.
