Debian is looking at implementing "multiarch", a way to have libraries
for multiple binary targets install in the same system root.

http://wiki.debian.org/multiarch

After amd64 systems, ia64 can benefit the most from multiarch. It would
be a shame to see this not happen.

I also agree with Bjorn that the propriatary tool shouldn't be the only
way. To the Intel people on the lists that work on this, what is Intel's
position on open sourcing this technology?

Thanks,
