lol :-)  I can briefly outline the current design.  Note the names are 
not really important.

libxen-hcall
  Library for exporting hypercalls.

libxen-idc
  Library for interdomain-communication primatives (providing the Sys-V 
IPC mechanisms seems like a reasonable start).

libxen-store
  Interface for interacting with the domain store.  Persisting daemons 
and these sorts of things link against this.

libxen
  Management tool interface.  Provide high-level functions that authors 
of management tools would expect.  In most cases, this would be all that 
would be needed to link against.  Developers can link against lower 
level libraries if necessary.

All libraries should use autotool, pkg-config, proper versioning info, 
etc.  All interfaces should be documented (this is a requirement of EAL 
besides being good practice).

We could begin work today on libxen-hcall and libxen-idc while we work 
out what the store is going to like and how the OF structure is going to 
work.  Thoughts?

Anthony Liguori
