Yes Rav,
They're not punter's are they?... however, as well as Amazon, others like RESMED, Philips, etc etc could invest but choose not to at this time because (I guess) that after all, we are just a 'start-up' and they will wait for results first then show interest if they so wish. They won't get involved spending money on unproven theory. Also, it might be worth waiting and watching if they are party to a take over of RAP, once results, and/or approval come in down the track.
All IMO.
