Another bit about the practical usefulness at this point: > The TCP checksum provides a series of additions and a comparison at the cost of hundreds of machine cycles to send and receive messages, which makes it computationally inefficient. To make the model viable, the computation-to-communication ratio must increase in order that the computation exported by the parasitic node is larger than the amount of cycles required by the node to solve the problem itself instead of sending it to the target. However, it is important to emphasize that these are drawbacks of the presented implementation and do not represent fundamental obstacles for parasitic computing. It remains to be seen whether a higher-level implementation of a parasitic computer could execute in an efficient manner.
