An extensible remote display infrastructure is described that provides support for a competitive multi-vendor development environment. Application functionality may be partitioned to suit the needs of a given application and client-side functionality may be packaged in dynamic virtual channel plug-ins for remote display clients. Interactive coupling between the remote display clients and the dynamic virtual channel plug-ins may be facilitated by remote display client extensibility repositories. The remote display client extensibility repositories may be located within a communication infrastructure aspect of the extensible remote display infrastructure and, in particular, at a static virtual channel level. Dynamic virtual channel plug-ins may register properties, functionality and/or components with remote display client extensibility repositories at available granularity.
