Re: [Anima] The layer 2 ACP

Clearly, the availability of a Layer 2 ACP would enable a community of
people who would like to experiment or develop, but who do not have
access to 1000+ processors.

Also, it seems to me that the "initial conditions" for a Layer 2
solution (preconfigured VLAN ID, password, etc.) are likely to be the
same as those for a geographically-distributed overlay solution.
Development of a Layer 2 solution could help/encourage the development
of an "overlay ACP", which could ease the development of new Autonomic
Functions.

So, given that I am a university professor with limited resources, I
think that this proposal is a *very* good idea.
