Other possible MBone PC specification - FreeBSD

	Video Card      : Video Card which could run X windows
			  (eg. ATI, Tseng series video card)

	Video Grabber   : Creative Video Spigot, Matrox Meteor,
			  Connectix QuickCam

	Sound Card      : Sound Blaster series, Gravis Sound Card series

Remained Problem

In simplex mode(sending only mode), it is possible to display and send with 1Mbps, But in duplex mode(sending and receiving mode), display rate of received data(frame per second) is dreadfully degraded. (You might want to see Appendix)
