1. No discussions about twins v. singles. The reason is, the IKAR is a worldwide organisation with different flight rules, authorities, and laws. In the US there is no pressure to use twins on such ops, in Europe i hope the described accident should be the last short haul accident with a single, because nearly all countrys have accepted the actual JAR-OPS 3 and the coming JAR-OPS 4. JAR-OPS 4 will have concrete and specified regulations about short haul ops.
2. No discussions about throttles and design, only about flight manuals and ops procedures
3. No disussions about hoist v. short haul, because the accident is a technical failure on the helicopter.
The hoist v. short haul discussion seems momentarily going to the short haul. It isn't a questions of possibilities and advantages, it's a questions of costs. In austria as example, nearly all rescue helicopters have decided to use the short haul.
