Multiples WebHooks for differents namespaces

Hi! It would be nice posting on different webhooks over differents namespaces.
For example, if namespaces are likely "namesp1,namesp2;namesp3", and webhooks something like "http://webhook1;http://webhook2",
when and event (editing, creating, and so) over namesp3, it hits "http://webhook2". On the otther hand, if namesp1 or namesp2 triggers an event, it hits "http://webhook1"
