I'm looking for an easy way for a large team (several dozen people) to keep each other informed at a scientific conference, using their phones, laptops, or other mobile devices. Anyone in the team should be able to post a message to a Web page -- which anyone in the team (or in the world) can read, most recent first. That's all the functionality needed. It's an AIDS conference, and we want activists and community writers to inform each other ASAP when they learn what is going to be important.
There is no need for confidentiality -- nor for person-to-person communication, since that is already available through text messaging or otherwise.
And there may be no need for spam control, since the 4000-person conference only lasts four days (March 3-6 in Boston), and the page to post on will not be announced publicly but distributed face-to-face before and at the meeting. But in case there is a spam problem, it would be helpful to be able to limit write access to IP addresses in the Boston area -- and/or to require a password or PIN to post. Anyone in the world can read the messages, that's no problem.
Here is the most difficult requirement. This project will not work if it requires any registration, or a Google, Microsoft, Apple, Disqus, etc. account. With only four days and people already busy day and night for the conference, too many won't get around to registering, saving and using a new password, etc. But they will bookmark a Web page that they can click any time keep in touch at the meeting. And that page could include a form for adding their own message.
I could write a Python program myself to do it (running entirely on a server and compatible with any Web device), but probably not by early March. Does anyone know of suitable software already available?
