Subject: Send over raw socket?

Hi,

This should be simple, but it doesn't seem to be documented anywhere I
can find...

I want to send data over a raw IP socket - not TCP or UDP. Ideally I'd
like the OS to provide it's IP header, but I can do that myself if I
have to. Normally you would open a socket as PF_INET, SOCK_RAW,
(protocol number), then use sendto, but sendto doesn't seem to exist in
ruby, and the Socket#send instance method is not documented anywhere, so
I don't know what arguments it needs.

Has anyone done this before, for any protocol? Oh, and to save time, I
don't want to use libnet or rubyforger or *random-lib-someone-wrote.

Thanks!
