I have DSL here at my moms, and wireless at my dads.
I don't think they cap KaZaA's speed tho...I mean, when it's connected (all the time, unless im just turning on the comp) my connection says "Connected at 100.00Mbps, whatever that means.

Megabites per second?
But I get kazaa songs going over 100kb/s sometimes, not just 25...for me, 25 is really slow.
