Sounds cool, but I have a couple of questions:

1.  Is it OpenSource?

2.  I assume since it never swaps to disk the memory requirements for the
    computer are large. What is the minimum suggested if one runs say
    5 apps that each require 16M each, 5*16M & OS overhead? And what is
    the suggested OS overhead with no swap to disk?

    (OK, that last one might be a 3rd question)
