By "default", the kernel shares bandwidth by connection, not per user
(this is not Squid specific).

No, if one is downloading several different files (or using P2P
software), they will get a disproportionate amount of bandwidth.

You can set a limit per IP address as Landy is doing, but it is better
to use tc (and SFQ) to share bandwidth per IP address (using "flow hash
keys nfct-dst divisor") as per the website above.
