Narrative:

We landed runway 27 at bos and turned off on taxiway K and we were switched to ground. Ground cleared us to cross runway 4L on taxiway K. Ground then cleared us to proceed on taxiway K and turn right on taxiway a. Approaching taxiway B; I noticed an aircraft on taxiway K pointed at us (opposite direction) on taxiway K just west of taxiway a and north of the main aarf. His taxi light was on. The captain stopped our 757 with the nose just past the east edge of taxiway B and set the parking brake. The other aircraft either began taxiing or continued taxiing toward us as if he didn't see us. As this aircraft approached taxiway B; he began a left turn onto taxiway B still taxiing as if he did not see us. The captain turned on all our taxi and landing lights and shouted 'stop; stop; stop; stop; stop!' on ground control frequency. At this point I recognized the aircraft as another air carrier's md-80 series aircraft. As he continued his left turn; I thought his right wingtip was going to hit our cockpit. The md-80 pilot steered left of the taxiway centerline and I observed his left main gear on the very left edge of the taxiway. (I later thought the gear was going to hit one of the blue taxiway lights). The md-80 right wingtip passed an estimated 10 ft in front of our nose. The other pilot never acknowledged our calls and never slowed his aircraft. After the aircraft had passed us and continued north on taxiway B; ground control told us to turn north on taxiway B rather than north on taxiway a as we were initially directed.
