Re: how to extend a capability on a data source?

In addition to David's point - eg
http://eros-os.org/user-history/rob-withers#!anotheunthaoentuhanotheusnatohesnuthasdothensausedvorak
- if you want to do attenuation, revocation etc within the system,
you've got to implement that.  I think we started down the path of
discussing how best to implement a cuspy capability system on top of
such a database, but never got very far.
