lzma with TCP/IP and libertas driver... and still some room

[Jim Gettys]

Yeah, and the other headache in IPv4 is lack of autoconfiguration: you
need a dhcp server for two machines to talk to each other.  If we want
to clone systems from nearby kids, this then means a dhcp server, and
all that rot.

Having personally had my home network hosed when a little sipura voip
box I had decided it would be nice to also offer addresses, this scares
the bejezus out of me.
