Folks, please understand the dynamics of the mobile market (all those iPhone / Android applications). By our estimation, there have been well over a million downloads of these applications over the past 7 months or so.
Some things to keep in mind. First, many of the user agents aren't "correct" - some of the mobile clients use programming methods that "look" like Internet Explorer, or Firefox, or Safari etc, so they are reported as such. Second, the applications pass across feeds very very quickly, due to the audience. Most of the mobile market listeners will listen to a feed for only a few seconds and then move on (we watch this behavior happen often.)
I'll look further into each of our relay servers and do some investigation, however you have to understand that on your end you aren't seeing directly what is occurring on a constant basis. On the LAPD and Chicago feeds, we see listeners come and go on those feeds on the order of hundreds a minute.
Scandxer, I watched over 30+ unique listeners come and go on your feed in about 3 minutes.
I'm not say there isn't an anomaly in place, but I can tell you there there are a LOT of variables to this equation and the sheer amount of transient listeners is one of them.
