Take a step back
and

look at it as a
Network agent
That when connected
updates on his trading-partners
as to who has and what you found
and during the day serves its voluntary limit
and blows it at night
defined as you whish in your daily planner
with your chosen logic plugging (what's the interface)
is there a phex Javadoc ?
how about an ant tutorial, getting started ...?
and then during the day forget all but your best traders
that you know and you didn't remember eliminated
from viewing the tree of files that you remember being traded
at which partner
and put trust your hearty friends that you recognize
an commercial trade with encrypted credit network cash over vpn
Banking with trust systems
Boy or Girl that's a tough one ...

cheers
