[jdev] Pseudo PubSub Node

Good day to one and all! I want to know if it is possible to make a pseudo or temporary node. Use case: I am building a system which provides API for both HTTP and XMPP. HTTP: http://eustace.i2p/feed/tag/mullins XMPP: xmpp:eustace.i2p?pubsub;action=subscribe;node=tag:mullins Both requests retrieve cached database entries tagged with "mullins". Both HTTP pathname and XMPP node do not exist. Concerning to XMPP, is it possible to do as follows? 1) Receive a request to read a PubSub node. 2) Check whether the requested PubSub node exists. 3) If the requested PubSub node does not exist, create it. 4) Populate the node with items. 5) Send a positive respond. Best regards, Schimon
