Another fact about Derby.
Derby is fully DB2 compatible (sql and jdbc) and you can switch easily to a 
"DB2 Community Edition" which is the full powered db2 product without 
clustering. 

But I dont want to produce additional work and this is not an extremly 
important question, so I will leave the decision to the other members and 
not slow down the development process 

Final Vote: +0 on H2 and Derby
