Oh my my ... i said : \"in the future\" and \"where everyone player have at least 512kbps bandwitch\" heh it was my dream ... however the technology is developing so fast that i wouldnt be suprised if after 5-10 years from now you could play PS on your wearable jacket PC
with the voice chat

(bah! the technology would allow to do it even today but it has extremely high price)
Returning to the topic :
Midi music would be nice - next flavour to PS realm, its good idea because dont require wide bandwitch for music data transfer. Well .. there would be need for muting some bad musicans

but the songs in tavern or
music played by bards while others would be fighting, could be something i would like to hear in game someday.
I dont know much about music creating but i suppose the medieval instruments midi soundbank could be good idea also.
