Sounds fine to me. We did recently post a "efficiency patch" for Itanium2
that was processor-specific. But in that case, we have Roberto to provide
support for it. (And here as well, the transition to Amber 9 will be

Whether we post this on our site, or just have a link to Apple's site, we
should definitely indicate that this is unsupported...if people have
they will probably just be directed to revert to the "real" pmemd code.
On the other hand, there are some very experienced Amber people out there
have access to G5 clusters, and if we can make their simulations faster,
would be a Good Thing.
