A general purpose natural speech recognition user interface in multiple languages?
Natural and seamless, general purpose parallel processing?
An operating environment that blurs the lines between local and distributed (cloud, clustered, whatever) computing? An operating environment on top of a virtual machine (pay attention: Sun/Oracle and Microsoft know damned well what they're doing with Java and .NET, and hypervisors/virtual machine monitors, while established, provide logical partitioning and nothing more) that transparently locates and consumes remote execution resources?
