Somehow, the vision of you running around a wedding with a toilet paper dispenser on your belt just doesn't make it (or maybe it does) -snip-

I knew this would spark some teasing.... and was certain that if you didn't say something, someone else would!
I'm not saying I'd do that at a wedding. Sheesh. If I were shooting a wedding, I wouldn't use my point and shoot and therefore would have no use for an on-camera toilet paper flash diffuser.

Ditto to what everyone else has said.
Just remember, if the lighting is "good enough" for a "regular lens", (say like a 50 mm lens working at a 3.5 f-stop), then it's probably OK for the telephoto lens. As Debbie says, the most important factor here is the f-stop (which is often smaller in telephoto lenses, and thus, more important to have fairly bright conditions). Also, a major convenience of digital cameras is the ability to increase the sensitivity, ISO, to be able to get the telephoto shots in less than bright conditions. (However, overdo the ISO and you'll notice that noise becomes objectionable--it's a tradeoff that only you can evaluate [get a "noisy" picture or no picture at all].)

Re: Need a flash or not
One important difference to keep in mind on the lens length is that while f8 at 1/50 may be fine for a 35mm lens (mild wide angle), trying to hand hold a 200mm lens at that shutter speed is tough (even with a stabilized lens) since a telephoto lens not only magnifies the image, it also magnifies any motion of the camera during the exposure. There are a whole range of techniques to try and hold longer lenses still while shooting. As you can see, there is no simple single answer to the issue This may be where the idea of needing a flash with 200mm or longer lenses started.
