Think so yes. I'm still not clear what the difference is between the
db_locator and the biodbname.

I'm not convinced here that you gain flexibility - you still have to have
code to fetch stuff somewhere. Your way you have to specify the method
name as well as the module name and in our way we just have one module per
method name. I'll go away and muse about this some more.

The system would work with or without the IOTable I think so I'm happy to
go with this.

And so as the stripey-winged owl's genome of Fate
is decoded by the great sequencer of Time,
and as the big grep of Eternity uses all the cpu of Destiny
I come to the end of the mail.
