I think dynamic bandwidth allocation would be a good idea, but I don't know if it's possible. Many accounts with a large number of SP are intended solely for the storage of SP, or to vote occasionally. These accounts could make their bandwidth available for the most needy accounts.

There are also thousands of accounts with a little bit of bandwidth but which are completely abandoned. A system to dynamically allocate this unused bandwidth to the most needy would really be a good thing.

Of course this solution creates another problem:"Who will benefit from this dynamic allocation?" and "How do we determine its attribution?"
