Have you considered Mercury RACEway ?  Presently with Intel i860
processors, soon with Analog Devices 2106x and PowerPC (603e?).
RACEway is a crossbar setup.  Up to 16 processors per VME board,
up to approx. 20 boards per 19" rackmount chassis, can span
between one chassis and another.  Much bandwidth, but don't know
how it compares to T9000.
