Thanks Chuck,

I think I'll just go the rsync route. I'm very familiar with it. I don't
particularly want to install it on the boxes I'm concerned with
momentarily, but I know how it works.

Your other option seems intriguing, but I'd rather not install more
software on these boxes if possible.

I was hoping for a magical, don't have to install anything-type solution :)

Perhaps I left out an important piece... even though I'm copying
directory structures, in many cases the bulk of the data will be
contained within massively large individual files. (Hence why rsync
wasn't my original choice).
