I'm using the excellent YCCC SO2R box. It includes WinKey emulation. It 
switches the keyer, mic, computer message playback, PTT, and headphones 
between radios on the basis of OTRSP or MKR2 commands via USB from the 
logging computer. I use VOX rather than the PTT function, because I 
don't like foot switches.  Mic, keyer, and headphones are plugged into 
the YCCC SO2R box. I use a Tascam US100 stereo USB audio interface for 
playback and for digital mode encode/decode.

It should "work" in the sense of switching the mic, playback, keyer, 
PTT, and headphones. But how does the user interface with the radio 
controlled by the second computer?  And why do you want the second

Not unless there's something within N1MM Plus to sense your foot switch.

Until the most recent NAQP RTTY, I used a setup somewhat like yours for 
SO2R RTTY contesting -- one Thinkpad per radio. Logger Classic and 
Logger Plus "sort of" prevent both rigs from transmitting at the same 
time, but it's a bit awkward to use.  To use it, I rearranged the 
operating desk enough to fit in the second laptop, moved the RS232 cable 
and audio cables from one computer to the other. Each computer had its 
own USB audio interface.

I recently upgraded the shack computer to a much faster processor with 
more RAM and more screen, so I tried running RTTY from the single 
computer. I was able to run two decoders on each radio, with enough 
screen real estate and processing horsepower, and I found it MUCH easier 
to use.
