Recently, I've decided that I'm going to make the switch from a 1.5Mbps T1 connection to much cheaper DSL connections. I've been looking for a "Broadband Bonding" technique which can bond anywhere from 2-5 DSL lines together to match or exceed the T1 I currently have. I've looked into the usual suspects such as Cisco, Juniper etc and the lesser known ones such as Mushroom Networks.  I am quite interested in purchasing a Mushroom Networks box after reading their marketing material (they also offer 30-day money back), but I would first like to learn your experience if you have one of their boxes. Does it really bond without requiring telco's help?
