well... technically.. it is just a crappy projector
so I guess it could be 100 feet.. if you held it back far enough.. and had a big enough wall

It doesn't work. Don't bother. Even if you can get it focused properly, a television doesn't have enough lumens (light) to produce a watchable 100" picture.
If you don't believe me, do this. Take your 27" tv (or whatever) and move it over to within a few feet of a bare white wall. Do you see anything on the wall? Pretty dim, right?

Here's the instructions you'll get, in brief:
1. Buy a page sized Fresnel Lens. Do a search, they're cheap.
2. Turn your TV upside down.
3. Hold the Fresnel Lens in front of it: Voila, it projects the image onto the opposite wall. Move the lens closer and further to focus.
There's refinements, like building a box to hold the lens and maximize the amount of light coming out to the wall, as well as making it easier to focus.

Here's a picture of their newest construction, which they call "Big Woody".
Projection quality? Let's not joke. You really get what you pay for. That Big Woody is scaled to use a 13 inch set.. Crank the brightness up and you can get something that is watchable in a dark room. Here's a link to an image of ConAir on their Big Woody: http://www.bstvcentral.b0x.com/conair4.jpg

Ehh.. That's not a terrible price the ebay guy is offering. He includes the Fresnel Lens, and those are fun to play with. I did this sort of project once with an old 13 inch TV and a cardboard box. It's entertaining, if worthless.
