... we talked about in our meeting that we were gonna have two
separate downloads, one for 32-bit, one for 64-bit.  If so, what will
be the basis for somone to be able discern which one they need to
download?

I assume you want to call them "5.1/32" and "5.1/64" because you want
to support 32-bit for years to come, and so the "5.1" names the image
contents, while the "32" or "64" names the word size.

That buys me a lot more time to upgrade Magma to work on 64-bit, and
makes sense if we really are going to support 32-bit for years to
come, but as the RPi 3 is 64-bit, it seems like new installations with
new versions of Squeak are most likely going to go 64-bit.  I could be
wrong.
