I like the idea. I often wished we had logging capabilities for release version SWFs running in release players that are similar to what e.g.. log4j offers for Java applications (the reason it works in Java is that javac by default always compiles debug information for source files and line numbers into class files. They have no concept of a "release build" vs. a "debug build". Different VM, different features)

The use case Martin describes (error only happening in release player or only on specific machine configurations usually at the end user / customer) sounds too familiar. The way I handled this was to add some self crafted logging that accumulates log information and on demand sends them away using http... not nice, but works. But it also could be so much better.

So I definitely would like to see these logging features Martin sketched up and would be happy to help out.
