SPI???

Serial peripheral interface? Something about firewalls that block syn floods, killing your access to google maps in snow leopard? Stuff about fetching events for arbitrary windows, and watching the references expire?

Google has a lot of stuff on SPI, but nothing looks like a programming interface.
