One scheme we looked at for board rework used an interesting approach for directing heat at a specific location. It was a high-intensity projector lamp and a lens to further focus the hot spot. For situations where that wasn't quite sufficient, it included a little hot air gun but it was placed on the opposite side of the board to just provide that little bit of extra thermal "oomph". Items with low emissivity (like shiny metal shields) didn't work too well but it was OK for soldering IC's.
