This approach can produce low-emittance bunches at high energy, easing the muon-cooling and acceleration challenges in such facilities. However, the small (< 1 $μ$b) useable production cross section means that extraordinary beam-power and targeting challenges would have to be met. We speculate on what this might entail.7 pages, 2 figures, prepared for Proceedings of the NuFact06 Workshop, Irvine, CA, 23-30 August 2006Accelerator PhysicsProducing an Intense, Cool Muon Beam via e+e- Annihilationtext
