[Users] Interaction Presence Agent - Presence User Agent

Dear all, I have a question for understanding: I have implemented one OpenSER as Registrar and one OpenSER as Presence Agent plus XCAP Server 1.0.0. This is all working so far with newest SVN Release (Big Thanks to Ovidiu and Anca for the hint) of OpenSER. Now I want to deploy a Web-Front-End for user interaction with the Presence Core, because not all clients used are SIMPLE capable. User of non-capable devices should be able to just login and change their presence state. They do not necessarily have to be registered at the registrar, why PUA+ pua_usrloc on registrar side is no choice. I was thinking about another OpenSER deployed as PUA plus the pua_mi module for a solution. It gets commands from Web-Frontend via PHP, forwarded to the FIFO with pua_mi module. The problem I have now is that the messages are sent just once. Means a user changes his presence state, PUA sends a PUBLISH to PA but after the expiry the user appears to be offline. Is there any possiblitiy to let the PUA send messages constantly, when the user selects online - means all the time until offline is selected? I was thinking about many possiblities (cronjob or shellscript running all the time during online time and sending data to FIFO) but they are more or less just work-arounds.
