Now you can add Slideshare.net slideshows to your WordPress-MU blogs.
Get the slideshre-mu plugin here (just change the .txt extension to .php).
Drop the slideshare-mu.php file into your wp-content/plugin and activate it. If you are running WordPress MU just drop it in the wp-content/plugins-mu directory.
The usage is the same as it is for wp.com users:
Slideshows and PowerPoint presentations from Slideshare.net can be embedded into your blog posts and pages via a Slideshare shortcode. Shortcodes can be found by going to any slideshow on the Slideshare site and copying the following embed code:
The code can then be pasted into any blog post or page to make the slideshow show up.
