Been looking at the Cairngorm framework for building event-driven Flex apps --but the name: cairngorm !? means a Scottish mountain or something -- for months I thought it was some kind of computer virus, so I stayed away.
But if you like the flexibility of of mvc style event-driven programming and throw in an event flow process (so that the cairngorm-savvy geeks you hire can be useful on day 1) then this scottish mountain virus may prove useful. There are several classes and handlers you need to understand, but it's very linear and once you you grok the event-flow, the structured flexibility can help get you or your newbie hires up to speed quickly.
