The way I use to get offline mode is:
1. Open 2 wow's and have one logged in
2. On the other wow log in, you will get disconnected of course
3. Repeat until your battle net is finally unavailable

Before flaming saying this is useless, just think. If you are level 8 with no flyer or on a trial account
you can explore Kalimdor's mountains etc.
