Yes-- though I didn't elaborate on it. You need a packager that can understand, say, that a binary built for ARMv5 EABI can interoperate with ARMv7 binaries etc. Again, I've heard it suggested that RPM can handle this, but I haven't looked at it in detail myself.
That is indeed the case - as on x86, it used to be common to build the majority of the distribution for i386, and glibc and a few other bits for a range of ix86 CPUs.
rpm and yum know that i386 is compatible with i486, which is compatible with i586 etc, so it will install an i386 package on i686 if no i486, i586 or i686 package is available.
It does the same for ARM with ARMv3, ARMv4 etc.
That sounds plausible.
That sounds like doubt.
I've used rpm extensively over the last 10 years or so, both on x86 and ARM. I've built many versions of Red Hat and Fedora for ARM. My ARM machines here (including the one which is going to send this email) run the result of that - and is currently a mixture of ARMv3 and ARMv4 Fedora packages.
Only doubt in the sense that I don't have experience with it myself, but I'm happy to take your word on it since you're more familiar with rpm.
