I have no idea what XEPs to set up when dealing with other servers. I did not have to set up any such thing. Like I said, federation (server to server communication) works out of the box, at least on Debian.
I didn't just make this up on the spot, I've been dealing with these issues for years. So yes, I've thought about them a lot.
I used to run a prosody server on my home box. It is great software and a fantastic daemon compared to ejabberd (edit: Configuration-wise that is) but fat lot of good that does if you don't know what XEPs to set up when dealing with other servers. I shut it down because it was pretty much useless and I wasn't able to talk to my gtalk buddies from it anymore.
