Hi Pierre, As far as XAPI servers go I have given up for now, although MapQuest is running a more reliable instance[1] that may be useful, although they employ Ian's Java implementation as well so the same bbox limitations likely apply.
I am, in fact, working on a similar project in the Netherlands and for an up-to-date data feed for CCTV cameras I use the process described here[2]. I'd love to compare that to your approach, we can probably benefit from each other's work.
