We need a good demo application

[Carsten Fregin]

I would suggest a competition to get a useful high-tech demo 
application, using myfaces with tomahawk, hibernate and ejb3 or minimum 
a good mvc layout. Furthermore it should have some tree data structures 
and "in table editing". I would really like to see some solutions. I 
would donate 400 Euro as price for the winner or we split it up for 
first, second and third place to 200,100,100. Maybe i could get some 
more donations for it and some media interest, if there is any interest. 
The solution must be under open source license. Anyone likes the idea?
