ok, but here's the thing with having full plugin framework: what if
two plugins take mutually exclusive actions (I.E. one plugin has a
whitelist, it tries to answer the phone because it's the girlfriend,
but the other plugin attempts to send the call to voicemail because
your gps says you're in a movie theatre) who should win? I think we
need to take one step beyond independent plugins:
This could be handled through either ordering or priority, either would
work. There still needs to be a control center that receives the basic
message from the core code (e.g. incoming call), works out which modules
are interested in the message and then sends it on to them. If you are
using ordering then you would probably chain the messages so that if the
message was altered by one module the altered message would be received
by the next/./ If you were using priority then you could send the
message to every module at the same time and wait for all responses
before continuing.
Ordering would probably be easier both to develop and for end users
to manage. Priorities *may* by faster, although that's not guaranteed
by any stretch. The best solution would probably be a combination of
ordering and priorities. As you mention, although this would be a very
useful system a lot of the ability of it to be end-user friendly would
rely on a very intuitive GUI (or alternatively a system that is
restricted in such a way that a configuation GUI is not required).
