This patch is basically okay, but I have to pick a few nits...

This code looks good, and I think it will be able support unicast
subscriptions too, later on.

Please, no braces in a case.
Put 'sen' at the top with the others.

Please use c99 types instead (unless a field has a type like that in
some public standard). We hate camel case.
Also, I anticipate that we will want many more than 32 events. Lets
add a whole bunch of space here for future use.
