Yup, ping depends on location, connection, (and if you're on cable) how many people are on in your zone. Here's what I have:
400k (kilobits per second) down
(yeah, it's about the slowest cable you can get, but I am not the one paying for it)
In JKII, I ping around 70-120ms to most servers. Some I get awesome pings (20-50ms). So, because of my location, I may not be able to play on a low ping server out on the West coast, but I could play on one on the East coast.
