For those who use tunnelers like Glider & friends or whatever I just saw..
Basically you cant tunnel the glider key if too many sessions are sent to the server, your glider key will get locked.Glider 1.5.3 and newer use a different method of authenticating your key with our server. Rather than pawing away at IP or MAC address or any other foolishness, Glider simply tracks open sessions on a key. If you open too many sessions on the same key, old ones will start to drop off - and the key will show on our end as having old sessions drop. If this happens because you started too many Gliders on the same key, Launchpad will yell at you on the next start with the "dead session" help topic, explaining that the last Glider session was stopped because too many others were open.
We currently have a soft limit of 2 sessions for regular Glider keys and 4 sessions for keys with Elite. That means you can usually get away with running that many copies. Keep in mind these are soft limits and subject to change in the future: most companies would simply say 1 session per license of the software and we reserve the right do that in the future. Fortunately, we probably won't.
Just telling you glider key leechers since I feel abit warmhearthed today.
