You can't and shouldn't co-opt DatagramSocket for this. Instead, add a new kind of transport, a raw socket. This should be fairly straightforward and it would actually be a fairly useful addition to Twisted.

It'd be neat. I can't think of anything I'd personally be able to _do_
with it. :)

I'll second this recommendation. You need root privileges on most systems
to open an ICMPable socket anyway. Running your whole process as root just
so you can ping some stuff is kind of unfortunate.
