				I have been struggling with getting ui_* files to utilize the qcommon.h file.  Specifically I need to be able to access functions such as NET_OutOfBandPrint().  Does anyone know if this is possible?

				You can't, unless you hack the engine too.

				Can you point me in the right direction to hack the engine?

				System calls from the UI module to the main engine are implemented in the following source files:
ui_public.h -- enumeration of system calls (UI_PRINT, etc.)
ui_local.h -- prototypes of the system calls, e.g. 'void trap_Print(const char *string);'
 
ui_syscalls.asm -- enumerations (whatever?) for the Quake assembler (e.g. -2 for UI_PRINT)
cl_ui.c -- the main engine functions that are called when the system call is made, see the huge switch module in 'CL_UISystemCalls'
If you plan to use DLLs instead of VM modules, then you also have to modify 'ui_syscalls.c'.
Studying these files will give you an idea about how the whole system call stuff is implemented. Try to imitate what the already implemented calls do.
