A little late but you might be interested in https://github.com/asyncly/EventEmitter2

From the description:

FEATURES

Namespaces/Wildcards.
Times To Listen (TTL), extends the once concept with many.
Browser environment compatibility.
Demonstrates good performance in benchmarks

Answer 2

YUI 2 has something like that, I assume YUI 3 does too, but I haven't looked at it in enough detail to know yet. EventEmitter appears to cover at least some of your requirements, and is much smaller. Some of the other libraries on microjs events may be promising too.

Answer 3

Try RxJS.

This exposes power of Reactive Extensions and Linq in the Javascript. Example:

this.searcher = $(me._textboxSelector)
        .toObservable("keyup")
        .Select(function (_) {
            return $(me._textboxSelector).val();
        })
        .Where(function (str) {
            if (me._madeSomeHiding && str.length < me._minStringLength) {
                $(me._itemsSelector).show();
            }

This allows creating a filter on a list. So you can say if user typed 2 characters and stopped for 250ms then do something.
