I had always treated it as one-way, the ability to 'transmit' but not 'recieve'. Reading the actual Telepathy ability from the SRD, though...<br/><br/><div class="quoteheader"><div class="topslice_quote">Quote</div></div><blockquote class="bbc_standard_quote">Telepathy<br/>A creature with this ability can communicate telepathically with any other creature within a certain range (specified in the creature’s entry, usually 100 feet) that has a language. It is possible to address multiple creatures at once telepathically, although maintaining a telepathic conversation with more than one creature at a time is just as difficult as simultaneously speaking and listening to multiple people at the same time. <br/><br/>Some creatures have a limited form of telepathy, while others have a more powerful form of the ability. <br/></blockquote><div class="quotefooter"><div class="botslice_quote"></div></div><br/>Does seem to support your interpretation. Very interesting, and potentially very useful.
