<lj-include> and/or $include(url) - embed dynamic content in journal entries and layouts
Short, concise description of the idea
Allow users to include dynamic content in their journals while not exposing LiveJournal to security risks, by implementing an <lj-include> tag.
Full description of the idea
Many LiveJournal users already have access to off-site scripting languages such as PHP, which can be used to generate dynamic content without posing a security risk to LiveJournal. The implementation therefore of an <lj-include> tag, and/or its equivalent function in S2, would benefit many users.
When such a tag or function is called within a layout or entry, the server could access the remote document, and (if it determines the content has changed) pass the document's content through LiveJournal's existing HTML cleaner, and cache the content locally to save bandwidth.
