Ideally, it's best to operate with a margin. Whether it's a with equipment, people or mentally, it's always better to have the ability to do more than to try to do more than you can. Let me give you an example, imagine trying to send four different video feeds from a single output switcher. Believe it or not, it can be done, but not easily. The more unknowns there are, the more bandwidth that's necessary. Coming into a service and being asked to fix a presentation, and troubleshoot the projector, and type in lyrics, can't be done by a single person, on a single computer. You can create bandwidth through the inclusion of better equipment, more people, and more time. Miracles can and do happen, but don't depend on them. If you do, you'll be dissappointed. One more thing, if you're in a situation where you don't have adequate bandwidth, there's another concept you need to know. I was at a celebration for our church's 6th anniversary. At the end, they added a song that wasn't in the computer. Since it was "Grace Like Rain" and I had literally one minute to create something, I typed the chorus only. The reason was that the verses were familar--the words to "Amazing Grace". The term for this is "triage". It's a French word meaning separation. In an ER, the doctors must separate the people who are uncomfortable from those who will die without immediate attention. Knowing the absolutely most important things, in order of importance, can save the day. Paul
