I see too chalanges here:

* defining 'semantics that are relatively independent of the rrd details

* there are many (!) people and tools relying on the present
  interfaces

if you are interested in working in that direction, I would suggest
you create a prototype for the webinterface using perl with fastcgi
this should give you a good platform to write a REST interface for
all apart from the graph / fetch separation ...

cheers
