Option Symbols

-I have linux server w/ php, sql, all the normal stuff
-private/password chat room option
-video/audio
-if possible, a messanger type client software where you wouldn’t have to be on the website to chat..I guess the website/server would just be the ‘connection’ , if that makes sense…don’t want to use yahoo, msn or others. any other suggestions here appreciated.
this is going to be a private channel for business conversations, not a public website, so I’m assuming SSL will help me with security, also will password protect and htaccess the directory, but any suggestions for excluding ‘outside’ interception would be appreciated.
