Particularly for something like a database layer that runs blocking operations (reads from the database) all the time, Twisted does require changes to how things work. Someone made an SQLObject-like OR mapper for Twisted and they implemented a nice decorator to make the usage somewhat palatable: http://usrsrc.org/darcs/tada/doc/examples/taoBasicUsage.py One function with a bunch of yields is a lot nicer than a ton of functions (having to create a callback for *each* database call!). For my own work, I've generally chosen ease-of-coding over the ability to handle thousands of simultaneous requests on a single box. (Some have argued that multithreaded programs aren't easy, but I guess that's all a question of how one's brain works...)
