	There are actually some other FTL drives that have been
	postulated in SF.  You can find the canonical list at

http://www.clark.net/pub/nyrath/stardrv.txt

	The reason most jump drives in SF use fixed jump points
	is the reason given in Pournelle's "The making of the
	Mote in God's Eye".  Without the choke points mandated by
	fixed jump points there would be few, if any, space battles.
	Space is so freaking huge that battles can only happen
	by mutual consent, lacking such choke points.
