From what I've seen of QMAP it seems like a reasonable design choice to have a software component (rmnet) dealing with this, separate from the transport. And I think IPA is the 4th or 5th mechanism for transporting QMAP packets back and forth to the modem.
Downstream rmnet is copyright 2007-, and I know of interest in bringing at least one of the other transports upstream.
