Exactly right. @Home is for home, they do not want anything to do with servers or money making issues. They will NOT upgrade their infrastructure beyond this point, that's why there's @Work.
@Home/@Work was designed from the ground up very carefully. They planned the cap all along. It's a part of the system. After more than a year with the company and numerous meetings about expansion and change one thing has been clear from the beginning: @Home will not have anything to do with upload, it will stay low. @Work will handly all open upstream users (for a price between 120 and 3600 dollars per month).
Sorry guys, that's just the way it is.
BTW I know DSL isn't available everywhere, but it doesn't matter. @Home isn't going to give you upload ever.
