+According to the [http://www.geni.net/GDD/GDD-06-08.pdf GENI Design Principles (GDD-06-08 PDF)], 
+GENI must enable construction of slices that "arrange components into a
+representative network" in a way that offers "predictable and
+repeatable behavior".
+
+What requirements does this place on the component interface?
+
+ 1. '''Slice construction'''.  Is coallocation required?  That is, is it ever
+ necessary for an experimenter to allocate a defined group of resources
+ as an atomic unit?  Is it sufficient to allow experimenters to select
+ from whatever resources are available at any given time?  Or will some
+ experiments require some set of resources matching a defined profile
+ whenever the set becomes available?
+
+ 2. '''Slice fidelity'''.  What level of assurance is required for the resources
+ allocated to each sliver?  Of course a Component Manager cannot
+ guarantee that a component will continue to function at a given level.
+ Does the slice service need it to provide any assurances at all, e.g.,
+ for "exclusive access to some subset of resources" in GDD-06-08?  What
+ assurances are needed to "support strong isolation between slices so
+ that experiments do not interfere with each other", or to "provide
+ enough feedback about what resources a slice actually receives to
+ enable researchers to evaluate the validity of their results"?
+
+ 3. '''Policy control'''.  According to GDD-06-08, GENI will be "sustainable" in
+ the sense that it will provide incentives to contribute resources.
+ For example, contributing resource providers might receive in return
+ for "access to the resources of GENI as a whole".  The GENI Principles
+ also suggest that the GENI Science Board will "establish policies
+ about how resources are allocated to research projects."  What 
+ component interfaces and powers are needed to support these
+ policy control services?
