> The current architecture is buggy because it makes the assumption that only one stream can be in process between two nodes at a given time, and stream send order never changes.  Because of this, the ACK process gets fouled up when other services wish to stream files.
> The process is somewhat contorted too (request, initiate, initiate done, send).
