Just some warning here:
1. beware of the fact that classes may be "exploded" from jars in directories and pick up
the correct place, if "explosion" happens
2. the annotation can be incredibly long, especially compared with data sent across a remote
call, thus slowing down everything a lot. I would let an option to not use annotation for
best performance, or a use a tinyurl mechanism of some sort.

All the rest is to get annotations right, which is non-trivial but interesting :)
Have fun !

Simon
