Yup. There's a reason mobile devices that do have IR ports still tend to not be usable as IR remote controls. It's not that you can put the signal into them, it's that the power available to the emitter isn't enough to be useful for that. And, really, that's how it should be. I expect that the impact on the design of the NIT, or any other mobile, to add this would be pretty prohibitive.

I think it makes more sense to ask someone to build a wifi-to-IR gateway device, where you could send signals to the gateway via wifi, and then that device would have a remote-control-quality IR emitter for sending signals to your devices. You could then position that somewhere in your livingroom that was useful.

What might be nice, though, is a typical data exchanging IR emitter/receiver on the NIT. The kind you get on an E61/E61i/E62/E71, so that you could do data synchronization through it with other Nokia devices (not just other NITs). But I doubt we'll see that. And don't say "that's what bluetooth is for". Bluetooth has some issues that make it not a total replacement for IR data syncing.
