I'm glad that others were thinking about this too.

IMO it would be better if such a feature was in the grizzly or grizzly-
http module so that others can benefit from it (e.g. for glassfish
that would be a major improvement).

I actually already have a primitive implementation of something
similar for grizzly-sendfile, but it works only for connections served
by grizzly-sendfile (I'm using my own selector). If you are curious
check out SendfileDownloadsMonitor.java
