Force the visual editor to use ABSOLUTE URLs ?

Hello,

Please, would you know if there is a way to force my wordpress blog (version 2.8 here) to ONLY use absolute URLs ?
(And definitely give up on relative URLs)

The fact that wordpress badly deals with relative URLs is widely known, and it has complicated my work a lot.
Recently I had yet another illustration, while hyperlinks are correct when a blog note is open (fancy permalinks : root/date/post-name)… However, if I just open the category to which the posts belong , then the hyperlinks shown above the –more– tag will become broken (structure : root/category/date/post-name).
All that because of internal URLs automatically written like that ../ – I know I can manually fix that, and this is what I have to do all the time. I’d like to avoid having to do it manually.

If you know of a way to achieve that, even if it means hacking into the code and having to do it again with every wordpress update, I’ll be gladly trying it 🙂

Thanks a lot if you can help,
Best regards,
Sabinou
