Does anybody know how you can play Co-Op with a friend in Project Reality?

I don't think you can paly coop in pr.

Join an empty co-op server and vote to switch the map to what you want...maybe...?

Use Hamachi.

Yes. Hamachi is a free program that allows you to connect as if through a LAN.

Simply start hamachi. Create a new network and both connect to it. (For the first time only, you later simply use the network you already created)
Then start PR.
Select "create local server" (or w/e exactly it's called) in the singleplayer menu or let your friend do that.
Your friend (or if he hosted, you) then connect through "join IP" - you simply enter the IP you can find in the hamachi program.

Edit: oh, and to spare you some possible confusion: Remember to turn auto balance off. And if you only use few bots or many players, you might want to change the bot ratio, all within PR's server creation menu.

You should know your game's ip address and your friend should be able to join your game using it if there's no firewall interference.
