Jack 0.80 has been released, and some apps that requires 0.80 (like ecasound 2.3) have already come out.
I'm not quite sure of the binary compatibility; it should
somehow work.
Status of current jack is that currently it compiles on all arches,
but actually runs on
ia64, i386, x86_64
only (to my dismay, which I found by running on my Zaurus PDA).
Therefore, we probably only need to consider binary compatibility
with previous versions of ia64, and i386 packages.
