[wp-hackers] Why always absolute paths?

This doesn't get rid of the problem that Vinicius initially complained about. Right now you use a php function to get the correct url to the theme directory, etc. Changing the methodology to relative urls rather than absolute urls only changes what the function returns. It doesn't get rid of the function. The functions are there to give a uniform solution across all possible configurations so that theme and plugin developers can release products that will work no matter what the configuration is (even if an installation has changed the location of its wp-content folder). So the relative path way of doing it would have to return the relative path to the WP installation. So, if using relative uris for http://www.example.com/, bloginfo('wpurl') would echo '/' instead of 'http://www.example.com'. For http://www.example.com/blog, it would echo '/blog/'. The thing is, you haven't changed anything except the length of the string echoed by the function. This is because you can't depend on any single configuration being present.

How, if Vinicius is developing a custom theme, the configuration for which he already knows (and knows that it won't change), then there's absolutely no problem with developing a theme or plugin with relative urls. But WP will never get rid of those handy functions that allow developers to publicly release their work (unless it gets rid of permalinks).
