How would one access this protocol support, does the OS already support it, is it merely disabled?

Please have a look at this picture of the internals of the N9:

The NFC controller is the chip labelled NXP 44501 at the top on the right side.

About the software support the N9 firmware may have for the SWP protocol, I just have no idea.

Can you please clarify what you're saying here.

SWP is a protocol for communicating the NFC controller with the existing SE (secure elements). Therefore, a physical path between them must exist. Does such routing exist in the N9? Again, I have no idea.

By the way, UICC stands for Universal Integrated Circuit Card, most commonly known as SIM card. Any SE you wanted to use with the N9 should be within the UICC, as there is no eSE (embedded secure element) in the handset itself.

Please correct me if I'm misunderstanding you.

*via SIM most likely but possibly other options.

Exactly. If the SWP support is in place, just put a SWP compatible UICC card in your phone and that's it.
