SH4 & SH5 Clustering

It's been a few years since anyone has posted anything here on clusters 
using the SH-4.

Does anyone have results or experiences of building systems using the SH-4?

The SH-5 is finally showing up in silicon at 2.8GFLOPS,  400MHz, under 
1W/cpu. The caches are small at 32KB yet have a 3.2GB/s peak internal 
bus, the SOC's have DDR memory and 32bit/66MHz PCI. They look attractive 
for low power dense clusters/blade applications that won't be hurt much 
by their small cache size and the 264MB/s peak PCI interface. A 1-U 
could contain 24 - 32 of these and require only convection cooling for 
the cpu's. The DDR memory would be the "hot spots" and require some 
forced air cooling.
