I'm not too familiar with management.. is it possible for management messages to come in via the network socket? I think we should be able to store push requests via something like a hash..? Create an array of things which can be pushed, then if the array slot is not null, it's a linked list of all the requests so far? (assuming correct that we want to support multiple clients requesting) Then each request could be a store of the address that requested that push notification? Linked list in this case would be fairly cheap, and we wouldn't have to sort them. The hash enables fast lookup of each push notification without having to scan a single list for every push notification.
