CPDLC.
Have to agree with BIK116.8 on this, so far as it's use in the Pacific is a great improvement. OVER HF. However, the oz experience showed that where VHF is available, it is far more preferable to use that. It is much faster. But I can certainly see the day where CPDLC will be used in preference to VHF. You know when that day will be, BIK116.8? The day they take human pilots out of the loop. So be careful what you wish for. You may be a rabid controller-hater, but guess what? All that vitriol you spit at us (computers will be able to do it better than you etc) applies equally to pilots. So when we are both out of a job, with the ATC computer directly feeding sequencing instructions into the onboard FMS, you'll be able smile smugly and say "I told you so!". Be careful what you wish for.
ps. What language would you like the CPDLC instructions to arrive in? English, French, Basic, Java.............
