Direct access to table & queue storage from Silverlight would be awesome!

Session affinity is an important option for a number of scenarios, including rolling application updates for no downtime. I would like to be able to run two concurrent versions of my application (that is, two hosted services) behind a single VIP, with session affinity tying a user to a specific version. I should be able to migrate their data from v.old to v.new and flip their session affinity flag to the new service programatically.
