I think 10Mb is faster than any DSL plan currently offered to any retail customer and I am not sure that you can get even a 2Mb DSL plan (certainly not upstream). There are no caps per se - just if that if you go over 10G then you get charged at $4.95/500Mb I think. This is certainly much better than the 20c/Mb they were charging before!
