Ankh is the new Ore. Unfortunately the l4ore-driver in L4Linux hasn't
been converted yet. But there's the l4shmnet driver which connects two
Linuxes via shared memory. I haven't used that one in a while so things
might be unstable but it basically works by creating an l4re namespace
in the start script and giving it to both Linuxes via
l4shmnet.add=shmns,0x12 (and one with an additional ',create'). Then
there should be a network device in each Linux...
