I am appalled and disgusted at this mockery of my science. Why don't we all just shit in each others asses, now? How about if I peed in someone's hair? Or vomited on their crotch? This garbage has no place in the realm of science.
Now then, if I may address some of the issues at hand...
// *----- The Shit Catcher -----* //
The shit catcher was introduced to us hundreds of years ago by the Native Americans. While they of course knew not to shit in the water, shitting on the ground would sometimes bring about its own splash-back, from puddles, dew filled leaves, etc. Not a group to disgrace the earth, they invented the shit catcher, which would collect a shit's worth of shit for later disposal.
But eventually there were problems. People found that after a great feast, they wanted to both shit and rest. This proved to be a nasty combo, as the first generation of Shit Catchers had a limited poo capacity.
This led to the development of the shit catcher network, in which follows today's Client-Server networks. Client shit catchers are distributed throughout the land, and are connected to the Server shit catcher, via plumbing. Although this modern system gives up portability, people found that the increased comfort to be worth the trade off.
With the advent of Fire Wire technology, as well as Fiber Optics, and perhaps someday Teleportation, engineers predict that shit catcher networks will become even more efficient. While today's networks can pipe up to 0.6 dumps a minute (DPM), we expect to see performance of up to 6.0 DPM in the near future.
