reply to both:

i know for DoS or DDoS
but if network has good protection, like QuakeNet,
i think that max users allowed are 4 by same ip
thus its harder to flood very much...
especially if someone has good download connection 512k-1.5 Mbit

as for inet speeds, i know that there are no DSL speed that gives above 8 Mbit, but i know seeing people (rich kids) talk about high speeds for home use, and i even heard from
friend 1 year ago that in Nehterlands goverment voted
that they should bring OC lines to every house like you have phone line now... so its quite growing up with inet in north there...

we in worse countries on balcan get ripped off for some shitty conections...

i mean i know that some dude with 2/2 Mbit can surelly wipe me out, but does "war" between hight connections can be
acomplished?

i mean you cant ping someone with packet of 10 MB every 1 ms :P

its different that as stated above by Rounin, that many bots start trash 1 user... thats then more like invasion, but 1 on 1 is.. pointless ?
