With the Spark app for Mac, Windows and Linux, you can create your own login,
then use those details in one of many 'XMPP' apps for iOS and Android, or via the web.
However, until I can figure out a timeout issue adjustment,
the apps will be a persistent login and best option.
Domain to use: xc.i4atv.info for Spark and the various XMPP apps when registering / logging in.
