Yes... in fact, that solution makes me lose my cookies! ;-)

This is easy enough to do given that we are moving to RDF as our Service
Signature - it just becomes another metadata tag. However, we would
then have to add some code to the registry that stores lease times, and
this then makes some assumptions about what the underling registry has
to know about. Given that we are now trying to support both a MOBY
Central and a myGrid/Feta underlying store we cannot make "arbitrary"
decisions like this anymore... A non-lease mechanism does not require
the registry to "think", only to store the data that it needs and
respond to "come hither agent" calls.
