Oh, in this particular case I agree, the Karma company generates the karma and furthermore consumes it all as well. What I was referring to was a distributed model where users essentially 'sell' their bandwidth to others for a credit against using someone else's bandwidth in the future. In that situation credit generation is a serious issue (how does someone 'pay' for my bandwidth if they don't have any credits themselves?). Using the term karma in that scenario is a bit confusing I guess :) In an ad-hoc wireless network there is the concern that some users will be selfish with the bandwidth they use and provide. Solving the problem of credit generation will help in that situation and in the sharing of an uplink bandwidth. The main difference is that in an ad-hoc network simply being part of the network adds value, and the bandwidth costs are based on power consumption and actual throughput, rather than an upstream cost.
