Great with a ruling on if non-telepaths can talk back!
I think a lot of the ruling can probably be found in the spells regarding telepathy, as this is in fact the basis for Limited Telepathy:
Telepathy (5th level Mystic):
"...You can’t use telepathy to locate creatures to communicate with them, but once you’ve established telepathic communication, you don’t require line of effect to maintain it."
This indicates that to initiate telepathy, you need a line of effect, but once communication is established, you don't need it anymore (but you still need to be withing range).
I also wonder how easy it is to discover if a character is speking telepathically. For guidance here, we can look at Telepathic Message (0th lvl Mystic/Technomancer):
"You can send a short telepathic message and hear simple telepathic replies. Any living creature within 10 feet of you or an intended recipient also receives your telepathic message
if it succeeds at a DC 25 Perception check. You must be able to see or hear each recipient. The creatures that receive the message can reply telepathically, but no more than a single message can be sent each round, and each message cannot exceed 10 words. A technomancer casting this spell can also use it to send a message to a computer or a construct with the technological subtype if the receiving target is designed to receive messages."
For this specific spell, other creatures can HEAR the message if they succed on a (quite difficult) Perception check. None of the other telepathy spells gives any chance of overhearing the message. I would say that Limited Telepathy is more closely related to the Telepathy spell, but less powerful (shorter range and must share a language).
Basically, to detect if anyone is speaking telepathically, you would need to know telepathy exists. Otherwise, you wouldn't even consider another being speaking telepathically. I don't know how common knowledge that is.
Knowing that this character in question can communicate telepathically will help. If you see a Lashunta or Shirren and knows that these races can speak telepathically, you would expect them to.
This of course leads into the question of what Limited Telepathy looks like, to an observer. Do their antennae glow? Do they have to the Professor X hand-to-the-temple gesture?
Another thing I wonder is if it's possible to shut out telepathic communication. Using telepathy together with social skills (bluff/diplomacy/intimidate) might provide for increased efficieny of the action, especially if the creature exposed doesn't know about telepathy. It would also do for a lot of fun roleplaying.
Related to this, say that I form a link with an enemy, hides and then just starts being as annoying and threatening as I can directly into their mind. Could they block me out?
When I think about it, I think I would rule it as "It's as hard to block out unwanted telepathy as it is to block out someone yelling at you with sound." Even harder if you're not familiar with telepathy (Tinfoil hat might work XD )
