WordPress MU

I just stumbled across the livejournal crosspost plugin for wp and after changing one single line it works flawlessly (had to comment out the call to: template-functions-links.php
since wpmu doesn't use that.
I tested it and so far it's working fine.
You can grab it here:

bumping my own post to see if anyone has suggestions for how I'd go about making a filter that takes the anarchy video tags and converts them over to their respective "correct" usage when reposting to livejournal. I've got a few users that crosspost between 4 different blog hosts and want to streamline the video repost for them.

I'm not thinking it would be very easy to do but I'm willing to try if it doesn't eat too much of the cpu and won't slowdown everything.

Your thoughts?

How do you actually invoke cross posting?

After you enable & configure the plugin, write a post.
