[DotGNU]can we implement Java for our auth system?

[Jeremy Petzold]

there have been disscussions as to making a new pluging for do handle 
the auth system. I was wondering if it would be possable to implement a 
Java applet that will use the existing Java plug-ins in the browser. if 
this is possable, the we would only need one applet and it will run on 
any java-enabled browser.

is this a practicle Idea? If not, I will have to drink more coffie so I 
will be able to think more clearly :-)
