Subject:   Layer 2 ethernet encryption?

My apologies if this shouldn't be posted to this group, but I didn't
know of any other place where an open discussion among "friends"
could take place.  If I should take this elsewhere, just let me know.

Is it possible to encrypt ethernet packets so that all layers above
layer 2 would be encrypted?  The idea I had was to make a device that
could defeat a TCP sniffer by encrypting the IP headers.  Is this
doable?  Viable?  A reinvention of the wheel?
