Are you sure about the ARM port ? They seem to be concentrating MID efforts on Intel. And even there, they go as far as to openly say the MID version will not have PulseAudio support as it is 'not required' by the MID devices. VOIP applications on a RX51 are a natural fit for Skype but their commitment to Linux is flaky at best even on the desktop (seriously, will we ever see 64 bit packages ?). Me, I expect a too little too late approach on ARM netbooks, and then if they *do* come through it will be a pleasant surprise.
