Rune K. Svendsen 2002bceac5 Add Linux script to limit outgoing bandwidth used by Bitcoin 
This commit adds a Linux script that uses tc and iptables to
limit outgoing bandwidth to Bitcoin nodes. All tcp connections with
a source or destination port of 8333 are limited to the chosen rate.
It does not alter the incoming bandwidth. Additionally, outgoing
bandwidth to a host on a local LAN (defined by the LOCALNET variable)
is not limited.

README 

This is a Linux bash script that will set up tc to limit the outgoing bandwidth for connections to the Bitcoin network. It limits outbound TCP traffic with a source or destination port of 8333, but not if the destination IP is within a LAN (defined as 192.168.x.x).

This means one can have an always-on bitcoind instance running, and another local bitcoind/bitcoin-qt instance which connects to this node and receives blocks from it.
