Wrong; it complements jack very well. There was some talk about
merging jack into pulseaudio, though.

Yes, that's the normal use case if you're a pro audio user and want
normal audio apps to work.

Jack is low level, ie only single mono channels; it deals with
synchronization and interconnection among applications. Pulse is
higher level; it deals with streams, like 5.1 audio and is only
intended to communicate with the server, ie no interconnection. Both
do network.

They complement each other perfectly;).
