I decided why not call and ask. Imagine that! :)
The Tengo internet is metered, if you exceed your 24 hour allotment you will be restricted in some way. Either throttled or something else. Streaming is not allowed. You are limited to 2 devices at any one time. I did not ask, but I assume they might not allow a router to be connected. So basically it is intended for regular web browsing and email. This is about what I expected.
DSL is available at the pedestals through Century Link.
The cable TV system is their own in house community system. It is analog, not digital.
Additional comments are still welcome!
