A liquid container which supplies ink to its exterior until the ink is almost depleted and allows simple detection of the remaining ink amount, is constructed to distribute components of the ink even after a prolonged standing. The lens and the flexible frame are both available in a variety of colors. The system preferably employs inter-modular encryption so that the system can be distributed across a network if desired. The pre-load decision of what to pre-load and when to pre-load may be locally derived within the RAN-cacheProxy device, or in-coordination with a locally connected CDN device.
