A number of methods for including links to other parts of a drupal site and for including images (image assist being what drew this to my attentions) use relative URLs that then break when cross-posted to Live Journal. Is it possible to (perhaps optionally) parse for relative links and turn them into absolute links, or is this purely a problem for the modules that generate relative links?

The flipside of this is at http://drupal.org/node/178328
