Is there a python library out there than can allow me to send UDP packets to a machine (sending to localhost is ok) from different source addresses and ports? I remember that one existed, but can't find it anymore.

Basics of Traffic Generators Traffic generators are a way of injecting traffic into a network for utilization by other devices. A traffic generator is meant to look like a device on a network, so it can target devices in receipt of traffic. This means it will have a physical, typically higher-level address.
You should use a traffic generator like IXIA's http://www.ixiacom.com/ traffic generator for this. This device allows you to create test cases with different loads on the network, both pointing at your application and just overall network congestion. You can even simulate network attacks on your application.
You can spoof an IP address using Scapy library.
Here's an example from Packet Wizardry: Ruling the Network with Python:
#!/usr/bin/env python
import sys
from scapy import *
conf.verb=0
if len(sys.argv) != 4:
print "Usage: ./spoof.py <target> <spoofed_ip> <port>"
sys.exit(1)
target = sys.argv[1]
spoofed_ip = sys.argv[2]
port = int(sys.argv[3])
p1=IP(dst=target,src=spoofed_ip)/TCP(dport=port,sport=5000,flags='S')
send(p1)
print "Okay, SYN sent. Enter the sniffed sequence number now: "
seq=sys.stdin.readline()
print "Okay, using sequence number " + seq
seq=int(seq[:-1])
p2=IP(dst=target,src=spoofed_ip)/TCP(dport=port,sport=5000,flags='A',
ack=seq+1,seq=1)
send(p2)
print "Okay, final ACK sent. Check netstat on your target :-)"
