I spoke to the UKCFUG in London this evening. Al Manning was up first, he discussed a ColdFusion/Flex application, and using ColdFusion as a Flex backend. And then I introduced ColdFusion MX 7 event gateways; what they are, why they are needed, their architecture and internals, gateway classes and instances, and demoing various gateway types. A crowd of about 100 were in attendance, and lots of good Q&A throughout (and thankfully the venue was air-conditioned!).
