Assumptions:

• Review of "Relay Science Light" is complete (070605)
• "Project Lasers: Lasers" has been sufficiently covered for sodium lasers (070605)
• Review of "Measure High-order Wavefront NGS" has been sufficiently discussed (070605)
• "Project Lasers: Uplink AO" has been sufficiently covered (070605)
• "Project Lasers: Beam Projector" has been sufficiently covered for sodium lasers (070605)
• Review of "Measure High-order Wavefront LGS" is complete (070627)
• "Sense Tip/tilt NGS" has little controversy (e.g. top ranked approach is using the NGS HOWFS)
