Universal Binaries

I'm curious as to why you want universal binaries. In general,  
binaries produced via MacPorts can't be copied between platforms, as  
they need all the libraries they depend on. Sure, you can copy your  
entire MacPorts /opt/local tree, but outside of doing that it's quite  
hard to migrate the built products.

Given that, what benefit do you get from universal binaries?
