    44The GENI debate over slivers has always seemed surreal to me, because it cannot be a technical disagreement.  It can only be a disagreement about what is meant by the term "sliver".   And that is pointless because a sliver could be anything.   So it quickly comes down to one's views about the goals and scope of the entire GENI undertaking.   And yet at the same time, the sliver debate raises a crucial technical issue because it will drive the implementation balance between declarative specifications and code, which is a major architectural tussle in GENI.   I am being provocative here but please bear with me.

    6 In the Spring of 2008 several of us made a pilgrimage to CNRI to talk about GENI to meet some Internet luminaries and talk about GENI.   (That was the last time I saw Jay Lepreau, bless him.)   As I recall, Vint Cerf was eloquent and animated on the theme that what is (or was) new in GENI is describing and reasoning about virtualized resources and their configurations.   (Federation is another challenge, but that is mostly a question of figuring out how to use prior work.)

    88GENI is all about heterogeneous deeply programmable virtualized infrastructure resources, also known as programmable substrate.   These words are taken from my favorite GENI Vision slide, which is now five years old and which I have been using for almost as long.  (If anyone remembers the history of this slide, I would like to know it.)
