I see lots of good and correct answers to your first question, but none to your second, so here's this: I think this is a terrible idea. Why should you have to rebuild your software (particularly the release version) just to change the server name? Also, how will you know which version of your software points at which server? You'll have to build in a mechanism to check at runtime. If it's at all practical on your platform, I recommend you load the domains/URLs from a config file. Only the smallest of embedded platforms may not be "practical" for that purpose :)
