Hi Steve, I am using it outside of a DAW, in an IR loader in the effects loop of the 11r. As far as the IR loader goes, some of us (myself included) are using the Logidy EPSi (version C), it is a stompbox style IR loader with stereo ins and outs and really low latency. I have it in the 11r effects loop after the cab block (with cab sim bypassed). This is then returned to the 11r and 11r rig-output to my FRFR (zlx12p). You can find out more about it here:
Logidy EPSi Some other people are using the Two Notes Torpedo C.A.B. in the same way. The Two Notes unit has a couple extra things like power tube amp emulation, MIDI, multiple footswitches, and more flexible EQing, but it is more than twice the price (~$475 vs $200).
These units both come with their own IRs of cabs, but I have found the OwnHammer IRs to be much better than the stock ones, for me at least..
Of course you can also use these IRs in a DAW, but I haven't gotten around to it yet.
