Only if you've work with or on geas :)  GEAS currently uses s static IDL
to define the communication to the GEAS server.  That interface provides
access to the object defined in GEAS.

Python code snips (from the demo available in CVS - under objectserver)

    def add_country(self):
        c = self.database.newObject("country")
        c.setField("id", raw_input("entry country ID  : "))
        c.setField("name", raw_input("entry country name: "))

    def show_invoices(self):
            invoices = self.database.loadAll("invoice")
            for i in invoices.objects:
                print "invoice: ", i.getField("contents")
                c = i.getReference("customer")
                if c != None:
                    print "  customer: ", c.getField("name")
        except GEAS.ServerError,ex:
            print ex.detail

So at this time it's more of a traditional application using CORBA as it's
communication protocol.

At least that my understanding of it.  We're a pretty small team starting
to push pretty hard.  That doesn't give us any time to really get into the
guts of the other modules.  Yes, this is a bad thing.  But it is
the reality of the situation.  

It does seem possible that the server could be extended to provide DII
interface.  Andrew would have to comment on this.
