I think there are poseidus ones floating about, same with TLPD (though most I see require plugins or professionbuddy), and I haven't seen any aeonaxx. Easiest way to write for TLPD or aeon would be to just have it pop up an alert when it finds either of them so the player can deal with them manually easily.
There's currently an issue with Nespirah in the Shimmering Expanse where pathing breaks if you're too close to it (Nespirah) I had to edit my private profile to stay much further away from it.
