More regards to this: I am *deathly afraid* of communicating with web 
services during my apps' request/response cycles; you have no idea how 
long it will take for the service to respond back to you, and when 
something with the service goes wrong (after possibly minutes of 
waiting), it tends to go wrong in completely unexpected and magical ways 
(often you'll not even *get* a timeout!). Doing this kind if ish in a 
background service is trivial if this logic already exists in a model; 
its impossible if the logic is in a controller.
