Mapping Access

If we're compiling a list of Public Access TV stations, I'd like to know how we define "Public Access TV" stations. Do they have to have a TV channel? Do they have to make those channels available to ANY content created in the community? Do they have to provide access to programming slots for free? Do they have to provide equipment or studio access? Do they have to provide training?
There are at least 5 stations in Colorado which call themselves Public Access, only two of whom would fit my definition. One does not have a facility, training, TV channels, or anything the public can "access" besides a website with video content.

If anyone has any time on their hands, one day we need to develop a definition, and get ALL the Public Access Stations listed. That may be nearly impossible, in that the entire reason we need such a list is that there's no centralized place to find all this information in one place. A good start is using this list and combining the other efforts that have taken place, such as:

1. The ACM List: http://www.ourchannels.org/alpha.htm
2. The Video University List: http://www.videouniversity.com/pubaccess.shtml#Colorado
3. WikiPedia's List: http://en.wikipedia.org/wiki/Public_access_stations_(United_States)

Are there others?
