I am on dial up (I live on a farm in the middle of no where, no cable/etc), and though 99.9999% of the time this is a disadvantage, I found one thing useful out of it.
If you lag your connection very badly (I do this by resuming a large download) while on a flying mount, you can continue to fly around, even inside of buildings that normally dismount you.
Why am I posting this? Well, knowing you all, you can find useful tricks with this information. You could, for example, get on top of a rafter/lamp/any other ceiling-type object and gank those below you.
Not that this matters, but I asked my friend to tell me what it looked like on his screen. He told me that it looked like I was swimming very fast through the air, and then just stopped on the protrusion of the wall, near the ceiling. He said it looked pretty funny.
I hope this can help you pass a few minutes, and I hope you enjoy!
