Mod-up. It's a great article. SSP is a ways off from being economical viable for domestic/mass-consumer use, there are other applications (i.e. military) where the current cost/kWh is higher and SSP is more feasible in the short-term.
There's usually nothing wrong with the hardware, just the software/firmware. Trying using some third party firmware like DD-WRT on the WRT54G. YMMV, but I can't recall the last time I had to reboot mine.
