It would be cool if I could have a 
filter _scedule_ a command, and have that command executed as soon as the 
action that triggered the sceduling has finished. To take my mail-sound again 
as an example. I could have the filter scedule to play my sound. The command 
would be put in a queue if the same command is not allready in the queue. As 
soon as the mailfetching that triggered the filters in the first place is 
ready, the commands in the queue would be executed. This would allow me to 
play a sound on the arrival of email that matches certain criteria, but would 
only sound it once, even if multiple matching emails would arrive. If I were 
to attach another sound to another class of messages, and such a message 
would arrive too, the sounds would both be played, because the commandline 
differs.
