Yeah, I know ARM is bi-endian (pretty much all non-x86 archs used nowadays are) but the question is if it's actually enough to have a software base for it. NetBSD having an ARM port in BE is great but most arm stuff is done for LE systems since MacOS, and NT, and most Linux stuff is LE. This isn't that much of a problem in the free software world because we like to test things on obscure architectures but for the kind of proprietary stuff that you'd want to run on arm might have problems (assuming it wasn't ported AIX already)
