This is exciting news! We should devote the next SEEK meeting (after
the Link-Up workshop) on this.

As for (1): maybe this can go hand in hand with improved XML support
in Kepler. Could be a topic in the upcoming SEEK AHM..
To fully integrate with Kepler, Jenny should contact one of the local
Kepler developers and check in her code in this way (unless that has
already happened).

There have recently been a number of UI extensions, e.g., Rod has
added a QBE query interface actor. Also: I assume the SCIA tool is
implemented in Java, so the integration shouldn't be too hard.
