I don't know how much this security model means in terms of speed. We have
to wait for the Reflection API to be implemented and then test. I'm willing
to pay a certain price in speed even if i'm not on the net. I think even in
net-disabled mode, where the security restrictions are not so strict, i
like if java checks wether I may access a certain method on a certain
class. The ability to write my own member access control (see Reflection
API page 12) for an agentclass at hand may give me more flexibility in the
design of a simulation. The security model may also prevent me from some
severe coredumps in the development phase of the model and instead throw
exceptions.

yours,
Christoph
