Question about CI_Session

[eluser]korpirkor[/eluser]
I was creating auth module which is allow to login for one account only on one PC. Every profile has `my_session_id` equal to current `session_id`.
I solve it - in each sess_update() I assign new session_id to my_session_id and it works fine. Unfortunetly now everywhere is the Session class - must be also included the authorization module (or new session_id won't be assigned)

I have read something about CodeIgniter Session class on this forum (the say that it is unreliable) and replace CI_Session by "Native / Database hybrid" library

Thanks for response !
