This is a great idea. We’re planning on placing one or more of the stickers that come with the goTenna in-box around the house. We have a glassed-in front porch with sidelights next to the door where these fit nicely.
But we also have something that is a variation on the Little Library concept out front, our Nuzbox. It offer books, maps, a bench to rest on, and a neighborhood bulletin board. Slapping another sticker or two on it would also be good and be seen by the many people who walk by…
The explanatory hand or notice is another great idea. This will be a good way to advertise our backbone relay node to and from downtown Urbana once it’s up.
However, availability of specific signage for stationary relay nodes would be of real value beyond the small sticker’s capabilities. Having the stationary node terminology on the signage itself would alert knowledgeable goTenna users of the possibility to operate beyond their usual boundaries if they stumble across one this way.
