well you can have your own custom manager as an app
you can use the automagic loading of apps, w/o the need to change
core asterisk to kick off your background daemon
in the load_module function just start a new thread that is your CSTA
manager & have it listen on a port, for CSTA cmds
and in the unload_module  do your shutdown / clean up work
then just stub out the _exec function so it is useless from the dial plan.

The only thing that is missing in the stardard manager is a message queue
list that register listeners can see that allow other managers to listen in
on manager events ...
OR
you could simply register a callback function for manager on an event but
then you have to
be carefull not to block the thread that does the callback
