Tell you what...let's get our terminology straight so there's no confusion. The cable you've been referring is what's known as a VGA to BNC breakout. The VGA part comes from the fact that it has a 15 pin HD Dsub connector on one end. The HD doesn't stand for high def, but rather high density (to distinguish it from the older low density, 2 row serial 9 pin connectors). The breakout term is to indicate that your VGA connector is split out to 5 individual coax's with BNC connectors on 'em.
As for the distance of 6 feet, you're partially correct. Generally speaking, PC video cards are not meant to drive cabling longer than about that distance without getting into bandwidth problems. Also, most "off the shelf" VGA cables (15pin Dsub on each end) are pretty pathetic in terms of build quality. They generally do not use individual coaxs, but rather just a bunch of conductors surrounded by a braided shield. Trying to go longer than 6 ft results in a lot of crosstalk between the conductors and causes errors in the signal reaching the display monitor. With a breakout cable, you are assured of individual coaxs, so the distance can be considerably longer without problems. With only 15' of distance to cover, and using a really good quality cable, you probably won't have any problems, although a buffer like the P2/DA2 Plus would help a little.
