Will binaries built in 10.6 still run in 10.5?

What is a good way to build stuff for distribution?

More specifically, lets say my goal is to build something universal,
package it up, including any frameworks or libraries needed, and make
it something that can be safely distributed?

Right now, there's one package I'm trying to work on that does this,
and it uses a very non-trivial script to do a lot of otool
modifications to library and framework paths as it builds the dmg.
