<p>Does anyone know if silverlight plugs into chrome, or when they plan to support it?</p>

This guy have had partial success with silverlight in chrome, but it does not seem to be supported:

From The Microsoft Silverlight Team in the
silverlight forum
:
Hello, currently we don't have plans
  to support Chrome. We will support it
  in the future if it gains enough
  market share. Please understand, each
  browser implements the plug-in model
  differently, so it'll be a lot of
  effort to officially support a browser
  100%... By the way, IE 8 also runs
  each tab in its own process. If a tab
  crashes, other tabs will still work
  fine.
UPDATE:
Jon Galloway has just posted instructions on how to get silverlight successfully running on Chrome here:
