Unfortunately, this isn't going to simulate a T1 very well as a null-modem cable can only do 115200bps while a T1 can do approximately 1.5Mbps.
Other than the pf firewall mentioned by Aaron, I've done this previously with a VPN connection. For example, openvpn has a "--shaper" parameter which allows you to limit the speed of a connection to an arbitrary number of bytes/sec.
