If we do end up choosing a feature-based name, I think we could start with a base name like: (With credit to a thesaurus antonyms section...)
- Visible Service
- Obvious Service
- Overt Service
- Open Service
- Revealed Service
- Known Service
Then we could add "Onion" to distinguish Tor services when necessary in context.
We can also add:
- "Rendezvous", or
- "Extend" / "(OR)Port" to distinguish between the different onion
services.
I'd suggest that the general goal is to convey the value proposition and avoid abstract or ambiguous terms that require further explanation. Running through the list of suggestions:
visible: begs the question "to whom?" and whether a traditional HS is not "visible"
obvious: not bad, but begs grammarians to criticise it
overt: i like this; I like "flagrant" too. both of them speak to the concept that this is the complement of a "hidden" service
open: very good, traditional, positive word, but with overloaded meaning (the open service is closed for maintenance)
revealed: not bad, but grammar again. "overt" is better.
known: same criticism as "visible"; if you're shooting for this you might want to consider "attested" instead?
