So you could mesh a bunch of strategically placed routers/laptops/RPis/whatever and then get everyone using a mobile device to connect to that mesh but then you wouldn't really be in any better position than just networking the regular way and having wifi extenders or whatever.<br /><br /> But yeah, would be *cool* if you could get the mobile devices meshing so that the net would extend really really far. No idea how you would even begin approaching that, sorry.<br /><br /> </div> <div class="message_footer"> <div class="message_footer_links"><a href="lpost.php?webtag=DEFAULT&reply_to=41598.5&return_msg=41598.4" class="reply"><span class="image post"></span>Reply</a></div> <div class="message_vote_form" data-msg="41598.5"> <span class="rating">0/0</span> <span class="image vote vote_down vote_down_off" title="Vote Down"></span> <span class="image vote vote_up vote_up_off" title="Vote Up"></span> </div> </div> </div><a name="a41598_6"></a><div class="message" id="message_41598_6"> <div class="message_header"> <div class="message_from"> From: Mizzy<span class="message_time"> 7 Oct 2015 21:03</span> <div class="clearer"></div> </div><div class="message_to">To: Peter (BOUGHTONP) <span><span class="image post_read" title="Read: 7 Oct 2015 21:24"></span></span> <span class="message_count">6 of 17</span><div class="clearer"></div> </div> </div> <div class="message_links"> <a href="lmessages.php?webtag=DEFAULT&msg=41598.6">41598.6</a> In reply to <a href="lmessages.php?webtag=DEFAULT&msg=41598.1">41598.1</a></div> <div class="message_body"> For messaging there's apps called jott or firechat<br /> Using a mix of wifi and Bluetooth to mesh. havent looked in to the security though<br /> Or you could use RFC1149/RFC2549...<br /> <br /> Updated rfc<div class="edit_text">EDITED: 7 Oct 2015 21:04 by MIZZY</div> </div> <div class="message_footer"> <div class="message_footer_links"><a href="lpost.php?webtag=DEFAULT&reply_to=41598.6&return_msg=41598.4" class="reply"><span class="image post"></span>Reply</a></div> <div class="message_vote_form" data-msg="41598.6"> <span class="rating">0/0</span> <span class="image vote vote_down vote_down_off" title="Vote Down"></span> <span class="image vote vote_up vote_up_off" title="Vote Up"></span> </div> </div> </div><a name="a41598_7"></a><div class="message" id="message_41598_7"> <div class="message_header"> <div class="message_from"> From: Peter (BOUGHTONP)<span class="message_time"> 7 Oct 2015 22:08</span> <div class="clearer"></div> </div><div class="message_to">To: ALL<span class="message_count">7 of 17</span><div class="clearer"></div> </div> </div> <div class="message_links"> <a href="lmessages.php?webtag=DEFAULT&msg=41598.7">41598.7</a></div> <div class="message_body"> Thanks all. <span class="emoticon e_smile" title=":)"><span class="e__">:)</span></span> <p>I'm assuming if it was as easy as buying decent hardware it wouldn't be an issue, so presumably the number of people and/or size of venues make it either a logistical hassle or too expensive.
