This is presumably not compatible with the XSETROOT stuff that people
are already using (not a big deal) and much more of a load on the
person who's sending out bitmaps (since they need to open a stream to
anyone receiving them), correct?
I doubt it would scale well to, say, a couple dozen people receiving a
broadcast simultaneously, unless you're being really careful with
using lots of file descriptors. (And even then, the operating system
will still impose a limit around 60 at a time.) Or are you not
targeting this for broadcast/subscription use, the way XSETROOT is
done today?
