Scrambled for distribution?

Is it possible to scramble data so that the signal can be broken into channels based on an average over time? Usually in communication, the average is kept to zero using a known and syncronized psuedo-random sequence (a scrambler). Could the sequence be modified (by observation and modification or sub-channel) to allow distribution of data based on bandwidth capability? This would allow a bus with fast and bandwidth limited devices to receive and automatically segregate data based on bandwidth, on a shared line. This could also work for chained, bandwidth limiting, series connections, like analog repeaters.

Maybe for transmission, slower devices could disrupt the signal for faster devices, causing the faster devices to modify the sequence to correct.

The goal wouldn’t be signal speed, but signal distribution based on bandwidth.
