With a function resolver to pass in from the host, a whole host of function 
pointers and wrapper functions, I think you could make this work. It would 
be mess to do by hand, but with a tool to muck through the .OBJs (yuck) and 
build the functions... Another option (double yuck) would be to trick the 
linker into running and then build ("self" modifying) code into the DLL that 
somehow knows (another tool and multiple link passes?) where all the fix 
ups are and resolves them on load. (problem: your code can't be read only 
anymore)
