For the group: But 32-bit apps will run on a 64-bit install?

For Glenn: So, given the replies, are you sure you want to run a 
64-bit distro? You have a large SQL server?

So, better question for the group: What sorts of apps make running a 
64-bit install worthwhile?

- I'm guessing Apache will run very well either way. e.g. on 32-bit 
with bigmem / PAE.
