What makes you think that the nodes in an AUGraph would not actually
be connected under iOS?
Granted, you cannot connect to custom AudioUnits, but there are many
useful Apple AudioUnits to choose from, and I often find that I need
them.
Also, if all you want is a single mixer, then, yes, all your inputs
would be callbacks and your output would be a callback, so in effect
it's as if there are no actual connections. But, if you create a
graph that has more than one node then you certainly should have
actual connections in your graph. In other words, assigning a
callback only breaks the connection that you're specifying, but none
of the other connections are affected.
Perhaps what you're noting is that you cannot have both a callback
and a connection at the same node. You'd need some sort of T-
connection for that. I guess we need more details about what you're
trying to do and why you think AUGraph doesn't have actual
connections, and then maybe we can get to the bottom of this.

You could assign a callback to the input of remoteIO (or another
mixer) that uses AURender to explicitly tell your mixer to render
into a bufferlist. The nodes in the graph would not actually be
connected, which sort of implies there's little point in using a
graph in the first place.
