SQL Denali still uses the legacy naming standards of single-server named instances. Given that each instance on a cluster has its own IP address and Network name resource, there is no reason to require a two-part name (virtualservername\instancename). This legacy item is confusing, difficult to communicate to customers and users, and makes the product look unprofessional. The Cluster installer and SQL Browser Service needs to allow the creation of single-part instance names for clustered instances.
This is particularly challenging when using DNS aliases to relocate SharePoint databases for disaster recovery purposes.
