the key is "certain zoom level". Aerialways have usually their station buldings/structures mapped/drawn explicitly so the default endpoints should necessarilly be fairly tiny anyway to avoid obstructing the station building when rendered. > I know that can be mitigated by min length or something, but ultimately a > playground amenity and an a "adventuring" amenity for adults seems like a > very different thing - maybe there is a kid and adult version of a zip line - > and contained inside a playground (or park?) sounds like a good dividing > line. > > It may just be the same cable - but the expectation and purpose is a bit > different - things a 10 year old operates by themselves next to a swing set > and something I wear a Harness and crash helmet for seem different.

Not only the cable but all technical structures may be exactly the same. This one - http://wiki.openstreetmap.org/wiki/File:Zip-line_Tirolesa.jpg - looks pretty much like a playground thing and the expectation of the users is probably very similar like with a playground zipwire. Is it a playground? I don't know. min_age, max_age, maxweight, fee and other access keys would seem far more important than deciding whether to map it as playground=zipwire or aerialway=zip_line. What information do you gain if you make up your mind and map it as either playground or aerialway zipwire? If you want a specific playground=zipwire should adventure/climbing parks and ropeway parks get yet another zipwire type? Btw the playground-type zipwires which I see in nearby parks are around 50 meters, are the 10m types predominant in your place?
