Is there any interest in this? You have voiced interest so that is the first step towards. Depending on how things go in $work in the next month I will start looking at an implementation. There are three experimental TCP modifications (NewCWV[1], PRR[2], TCP Stealth[3]) that have implementations, but have not seen any discussion. These are only the ones I know of, there might be others. These patches didn't really get any discussion, this makes me reluctant to put time into an implementation if it is just going to go stale on the list.
