Mile High Tech
The subject of this name is the word "tech" which isn't a place or community. It's describing the wrong element of what is trying to be named. "Tech" should be a descriptor of the location or community. The double meaning is clever for sure, but as already mentioned, it has no sense of place.

I wish this one evoked more of a sense of place rather than a concept but do also like the double entendre.
Kathy Keating commented
Love this one as it has dual meaning. "Mile High" and 'High Tech".
