No, I'm afraid I don't have any plans for making maps, public pocket queries or event caches. Do you know how to make a map? Can I make my pocket queries public? I just used the zip code of the county seat. I was going to make a public bookmark list.
You can make a pocket query available to everyone by building a query then uploading it to site like file dropper. Maps can be made fairly easily on Google Maps. Any other tech questions you might have I can help you out!
