A nestable bottle crate provides increased stability to the containers and improved nesting relative to prior art crates. The construction further comprises separate access regions associated with the base region, emitter region and collector region, respectively. The hydrotreated HCN and ICN effluents may be conducted to heat exchangers to pre-heat the ICN feed, obviating the need for a furnace. The movable seal separates the osmopolymer from the beneficial agent. The switching device is connected to a controlling device. In one embodiment, a networked media playback device is configured to provide a web server for delivering data indicative of a browser-renderable control interface for the networked media playback device, or for a related networked media playback system.
