Apologies for being off-topic. <shameless plug> Project Page: http://sourceforge.net/projects/teleauth Public Service: http://public.paynacea.com If anyone is interested, I am currently testing my new two-factor authentication system and am offering the service for free. It does not use keys, tags or other special hardware since it authenticates a user by calling them on their land / cell phone and requesting a PIN code. The software has a comprehensive easy-to-use API (complete with documentation), and is designed to be highly-available. The client tools are open-sourced and distributed under the GPL. The tools include PAM modules (w/ binaries for Solaris, Linux and OS X), administration software and samples. If you have your own web sites, servers, VPNs etc. that you maintain; you might find this service very useful. Integrating the system with existing software, sites or services etc. is almost trivial. </shameless plug> More information at: http://public.paynacea.com If you have any questions, feel free to e-mail me off-list.
