Pity QNX is x86 only (and most definitely not open source). Won't exactly run well on a StrongARM. There are however plenty of RTOSes which *will* run on SA's, but linux is sooooo much cuter. But you know that :)

ps: QNX UK is about, ooooo, 50 feet from our office. We could probably shout at them from here and ask if they're doing an ARM port...
