Personally, I don't *want* a "full feature" bus!  I want something simple
and fast which doesn't make me use half the board (or expensive single-sourced
slow-delivery buggy semi-vaporware VVVLSI) for bus interfaces.  It looks to
me like the bus-design community is going through a delayed version of the
processor-architecture community's evolution.  The "full feature" buses are
the Intel 432 of bus design.  It's high time for a RISC bus.

(I may be being a bit hard on the NuBus; as I recall, it's not as bad as
the rest.  Multibus II and Futurebus are definitely 432buses, and VMEbus
avoids that distinction only if you ignore the more recent tailfins.)
