Theres a few on that list who are providing service to marinas, but in my
humble opinion... if you are planning on doing that type of setup, you would
need better bandwidth than consumer grade sat service would provide, and
knowing the typical marina customer, your customer base will be larger than
20%, also to consider is the geographic location, are you planning to supply
service over water? That is very difficult with 802.11b, is the marina open
all year or seasonal, etc...
