a GA is like a cryscal ball. It's main purpose is to try to predict the future

At first BL->BL communication seems more natural to me, but remembering
the pull\push systems I misjudged,   BL->DL->DL->BL comm. might be better.
This is something to think about in the (near) future. Nothing really important

Thnx Brad :) But serieusly, I see cristisism as a good thing because it will
make me do a better job. Let me list the functionallity of the BL again the way
I see it:

1. AAA (Authorisation, Authentication and Accounting),
        Authorisation = giving a user access to an system.
        Authentication = user+password system to get a network address space,
                                            cq an area where a user can run it's
        Accounting = Resources management (cpu\ram\HD space\etc)

2. Brokering,
        to spread and connect nodes (PL networks) across multiple systems

3. Optimalisation,
        a dynamic weighting system that predicts loads so the brokering can be
done better.
        Note this system  requieres a network of SINGLE type nodes, the +/- 120
diff. node
        types of the PL can never be 'compared' to each other.
