I am 98% sure that it won't work "out of the box".
IR transmitters don't all work on the same frequency, and even if they did, they're basically each speaking their own dialect of morse-code. So what you'd need for starters is an IR receiver that chats on the same freq. as the keyboard, and does no "intelligent translation" of the incoming message, but just passes the codes on. Then you could go ahead and decipher.
However, since the "Open" is a teletext unit, I'm very skeptic that it'll ever work
But then.. you may get lucky, who knows...
