 An unusual way to select a processor :)

 SPI are generally intended to be chip-select (SS) controlled.
The HW is so simple, and fast, there is little demand
for concurrent dual SPI.

Thus port pins, or a simple HC138 decode chip can give 8 SPI ports.

 If you do not want to parallel CLK.SI.SO, you could use a
SPLD (starting at ATF16V8) to HW mux as much as you needed.

The MSP430F14X somebody has already mentioned. Hitachi's H8S2144 has 3
serial ports, and is fairly easy to get into with free gcc and cheap
quickstart kit. Now even Microchip are doing PICs with 2 serial ports
(at last! what kept them ?) I would guess these can be used as SPI. The
Dallas DS80C320 has 2 async serial ports, dunno about SPI.
