If providing a 64 bit binary is a "port" for this product then I suspect you have more tough love forthcoming. Really, the rest of the universe can just "build" across architectures (and I recognize that you probably can't control your partner's code and need to do multilib for the games, but really -- you couldn't make it work on your own code?). But this thread is long enough already. Just realize that you're not inspiring confidence here... Also look at Skype on Fedora for an example of a 32-bit-only multilib aware commercial product.
