I'll paste the answer to Brian's question (from the comments of this blog post)
We plan to add this feature in Q3 2009 release of
RadControls for WinForms (a preview may be available earlier). And while we would want, we will not have time to prepare this feature
for Q2 2009 release. Any suggestions that you may have for this
feature are very welcome.
Regarding Ibleif's question, yes you could think of persons as resources in terms of RadScheduler (you can change the label beside the resources combo box if you want).
However, RadScheduler will accept any IResource implementation, so you could create a custom PersonResource class that implements the IResource interface and also has some custom properties and logic.
We will also consider adding support for multiple resource types in a future release.
