Another thing to keep in mind -- every time they make an interface faster or better, it either needs more expensive cables, or shorter cables. This is because, the faster the signal, the more it reduces with distance. Look what increasing the speed of Ethernet did to its maximum lengths:
They're trying to make Thunderbolt via viber optic popular, which can avoid this to a degree.

robot-pmaptest - occupancy grid map creation tool
SYNOPSIS
robot-pmaptest [options] <logfilename>
DESCRIPTION
robot-pmaptest is utility demonstrates the basic functionality of the pmap library and serves a handy mapping utility in its own right.
Given a Player logfile containing odometry and laser data, robot-pmaptest will produce an occupancy grid map of the environment.
OPTIONS -g disable the GUI (run in console mode only).
--range_max range
maximum effective range for the laser in meter (default: range saved in logfile).
--position_index index
index of odometry device in logfile (defualt: 0).
--laser_index index
index of laser device in logfile (default: 0).
--num_samples number
number of samples in particle filter (default: 200).
--resample_interval number
number of scans between resampling steps.
--resample_sigma width
width of resampling gaussian.
--num_cycles number
number of optimization cycles in the fine phase (default: 100).
--robot_x position
initial position of the robot on the x-axis.
--robot_y position
initial position of the robot on the y-axis.
--robot_rot rotation
initial rotation of the robot in degrees.
--grid_width width
width of the grid in meters (default: 64.0).
--grid_height height
height of the grid in meters (default: 48.0).
--grid_scale scale
scale of the grid in meters per cell (default: 0.10).
--laser_x position
position of the laser scanner on the robot.
--laser_rot rotation
rotation of the laser scanner on the robot in degrees.
--robot_hostname hostname
the hostname of the robot to verify in the logfile.
--robot_hostname hostname
the hostname of the robot to verify in the logfile.
--skip time
amount of time to skip between log entries.
--range_resresolution
resolution of the laser (only used inlodo, not lodo2 which is currentlyused).
--action_model_xx factor
believe factors in the change of the robot's pose.
--action_model_rx factor
believe factors in the change of the robot's pose.
--action_model_rr factor
believe factors in the change of the robot's pose.
