You CAN, of course, run two version on the same computer. (I do this
all the time, just give them different ports.) Those two processes
can talk via a pipe or shared memory (at least under Linux.)
I wonder if one could do some sort of hack by making multiple shared
libraries of PJSIP and loading it multiple times into an app? Would
the globals be segregated in their own area via the shared library?
