ok, so for whatever reason, getting Flex to move from dev server to live server has been the biggest pain in the butt.
See, here's what my conception of the entire process was:

Compile with local machine's services-config.xml file (that had the localhost and port number hard coded in it).

Get ready to move out to live.

Recompile with live server's services-config.xml file.

Hope for the best.

Some observations:

You can just compile with a services-config file in the directory your flex source code is in.
Leave the URL with the default {} stuff.

Move to your server.
That's it.
You can still use REMOTE OBJECT mxml tags.
FAR easier than messing with AS if you don't want to.

Ok, I'm back on the Flex bandwagon now. Having THAT big pain in the butt outta the way smoothed it out sooo much more.

Note: *I* did not figure that out. My coworker, Brandon C. did. So there.
