Tributaries offers up HDA140 1-in / 4-out HDMI distribution amplifier
We've got to say, Tributaries' T12 power strip was way more intriguing than this thing, but regardless of your excitement level, you may still need a distribution amplifier to send a single HDMI signal out in four different directions. The HDA140 is a 1-in, 4-out amp which pipes one HDMI signal to four zones up to 100-feet away; as expected, the unit is fully HDMI 1.3 / HDCP compliant and supports 1440p, Deep Color, Dolby TrueHD, DTS-HD Master Audio and refresh rates up to 120Hz. It's available now for $450.
