I don't object to choice in Debian, but I am wondering why VDE has been
created when there are alternatives like OpenVPN, tinc and GVPE, which
can all tunnel Ethernet over the Internet and work like a switch as
well. Tinc can even work with UML sockets (and since GVPE can use some of
tinc's components, it can probably be compiled to do so as well). Both
tinc and GVPE let you specify endpoints, both tools will automatically
create a full mesh of tunnels. The performance of OpenVPN, tinc and GVPE
will probably also be better because they use UDP instead of TCP streams
(like you would get with dpipe = ssh).

Renzo, perhaps it might be worthwile to combine your efforts with one
of these projects? GVPE comes closest to VDE.
