No, you cannot. There is no way of easily bonding the connection to a single IP address. Each connection would be limited to 1.5Mbit/sec. However, you can simultaneously download from two *DIFFERENT* web sites, at the same time, getting 1.5Mbits/sec from each. You just can't get 3Mbits/sec in one download. There are service providers that offer bonded connections (usually for dialup or ISDN), but that will require the cooperation of your ISP.
