We just launched the Automattic Support Network which is a place for companies to purchase paid support for WordPress and MU. Originally I didn't think we'd need to do this, simply because the WordPress.org support forums are so amazing and there is such a good community around it. That hasn't changed, but some big companies and enterprise folks are uncomfortable with volunteer support, and want (and insist) on paying someone before deploying a product. Based on that feedback and a lot of input from Podz, we put together this new product, which is basically VIP support with a guaranteed response time. Toni has some more thoughts here. We also rolled out new pricing for commercial Akismet use a few days ago, and the response has been great so far.
