Jeff, Andrew etal: 1. I vaguely recall this subject coming up 10 or more years ago, with the conclusion that a tool called a "bypass lopper" beat saws. This Amazon ad
http://www.amazon.com/True-Temper-Pruning-Solutions-2342530/dp/B000EM2SSQ/ref=pd_bxgy_lg_text_y shows at least 3 companies producing tools that seem to be about $15 per inch of wood material to be sliced (1.5 up to 3 inch). Mainly designed for use in the field, but clamping on a bench should be fairly easy for many, and it might do double duty. 2. I really know nothing on this topic - just repeating earlier dialog.
