at first - not for every file it is worth doing (only for very large files)
second - if you don't have more than one connection to internet (like
multiple dialup lines) it is pointless - and thus it obviously shouldn't be
_default_ option .

the main thing it is usefull for is listening to mp3's live from server
without need of downloading them - while still having ablity to cache them .

in this case even if squid will open i.e. 10 connections via all gateways
avaliable in LAN/MAN/WAN, overall bandwitch will be limited with bitrate of
an mp3 file played live .

i don't see this is 'antisocial' as otherwise users will just go for _faster_
download lines, NAT'ed like ADSL services which are common, and thus their
web servers will not have multiple IP adresses to load balance (ADSL doesn't
usually have static IP number, or - if it is shared ADSL - user will not get
any IP number at all, just ablity to download via NAT)

why having 10 slow static IP lines via different ISP's is better than one
fast ADSL with no ip number ?

because when user will establish own webserver it can be aliased on those 10
connections, and set up load balancing rule on his DNS server.

also - it would provide better failover mechanism, when one of servers is
down/overloaded, connection will continue over remaining ones
same is with ISP lines users have.
if one line is down/overloaded, and there is one not used at all, traffic
could go via it.
