    Chris,

    You can checkout Tachyon.net, they just launched *two* way broadband
    internet access over satellite in march. .9m VSAT dish. Traffic are carried
    over MPEG/DVB. Their service targets to small-mid size businesses and is QOS
    provisioned. They currently have coverage in Europe/North/South America.
