Good opportunity for plug!

I presented a paper at Ada-Europe 2003 titled "Ada, interfaces, and the listener paradigm".
It provides a design pattern for providing all the functionnality of Java interfaces, and can easily be extende to full MI.
It is available from the proceedings (Springer), but I can send it to anybody who's interested.
It is my intent to publish it on Adalog's web site as soon as I get around to it :-)
