traded session-scoped CFCs for something akin to a flyweight pattern
implementation. Our client variables setup is almost identical to
what CF provides, except that it allows complex values (because it's
serialized using WDDX, rather than the lists that CF uses). What that
lets us do is have a given client variable structure that would take
the place of your session CFC. Where you'd call a method on your
session-scoped CFC, we call a method on a shared CFC instance, passing
in the client variable structure, which represents the state that your
session CFC would have in instance variables. The operation does what
it needs, possibly changing the "instance" data from the client
variables, and then exits.
Because the state and functionality are separate, we don't have to
worry about serialization of the CFCs, or even tying them to specific
users. It's not really what the flyweight pattern was designed for,
but it works pretty well.
