I think a lensflare effect when a LAM is pointing at your face would be a nice addition to INF, similar to the one seen in Metal Gear Solid when fighting the sniper. aside from the obvious "cool factor" there is also the fact that it could blind someone for a second causing panic (especially if they see the laser before you!) I dunno if this is possible in UT but i know it can be done in 2K4 (See chaosUT sniper rifle).
