hi,
here are my comments:
-detailed information about aggregates:
components not only provide methods, they can hold data as well.
so you might need several components of one type, and you might want
to share them with other aggregated components. so the namespace that

I suggest using some kind of automaton. Most types can handle looping
and branching, and if they get extended or can run code or store data they
are powerful enough. Creating yet another way is probably not good for
the learning curve you talked about.
You do not really need a new session type. Mo

Hi,
I started work on an implementation for a Coloured Petri-Nets simulator.

be found at http://www.inf.tu-dresden.de/~tr16 . CPNs (or Petri Nets in

hi,
there was an update for PoCo::Client::FTP, available through CVS on

It's almost a beta, data connections are missing. The state machine

if you like we could certainly work together, although my plan is to complete
the scripting module and use it as it would make several things easier.

There are several POE::Relationship sub classes mentioned in the TODO file.
I'd like to note that these are patterns which should be layered on a
