Just wanted to follow up here that aonic and I conversed offline through email; he was very helpful. The skinny -- look at nginx + fcgi, design for separating read-only traffic (SELECT) from write-only traffic (INSERT, UPDATE), think about memcache early on but abstract it away. Another note from me: architect profiling into app and prepare to log everything because if you don't know where bottleneck is, you can't remove it.
