I do not know about any other sd adaptor.  However, we do have a
default adaptor in saga-core, which, at the moment, does nothing.
We shouod certainly be able to extend that one to read service
locations from a config file.  Together with the gLite adaptor that
should provide all we need for the demo.

Hartmut, is that something you could take on?

IMHO, iRods would be an excellent OGF demo backend, given the
consistent and strong OGF participation of the iRods developers and
users!  

Best, Andre.
