I'm still not following. There's no (sane) reason I can see you can't ship your own 64 bit binaries. Obviously some of your games aren't going to qualify, but you'll need your own library manager for that stuff anyway. Why must the client install be such a mess?
And again, I'm not part of the beta so I really can't comment on your forums. If I'm going to deliver tough love it has to be here, sorry.
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.
