As it comes to custom embedded systems, that makes sense.

But in the "normal" case, we have no control over /proc, and hence they are
mostly useless. Worse, we don't want to blindly enable TCP-level
keep-alives. In some cases, we have application-layer keep-alives anyway
(e.g. RTSP client). In other cases, we simply don't need them (especially
server-side). Sending keep-alives and even programming them in the system
timer consumes battery (and money if you pay-per-bit). Also, it forces your
peer to consumes its own battery and/or money.

I don't know about MJPEG, but I think we should refrain from using
SO_KEEPALIVE in the generic VLC socket code.
