memcached + Map Reduce/parallel processing functions

[philipmather]

Has anyone ever considered witting some sort of interface to
register a function to so that newly stored keys or values are
subsequently processed in parallel in the background with the output
being used to either produce a Tag (as you are proposing to add) or a
replacement value (with perhaps a flag to indicate that it's been
completed)?
I realise this is significantly adding to the basic functionality
and hence base purpose of memcache to the same extent as the
memcachedb for example so it might be a completely seperate fork or
mod_func style effort but was just curious?
If it were a "proper" (not entirely sure what I mean by that as
yet) parallel processing method you'd have to add some sort of
processing scheduler either to each node or to a designated master
node that would hence need to communicate with/manage/know about/
monitor the other nodes as a first step.
