pub sub question

[obruening]

hi,

i have two javascript objects, a knockout.js viewmodel and an object
that talks to a jabber server.

i want a loose coupling between both objects, they talk to each other
in both directions with amplify pub / sub. it works great and both
objects don't even know each other. do you think that this is the
right approach to do this kind of inter-object communication? another
approach would be to pass the one object to the other. but they would
need to know each other in both directions.

best regards
oliver
