Spike the creator of FTE Quakeworld has released a streaming MVD QW Proxy called FTE Quake TV which allows people to steam games in MVD format (demos or live games). Here is a breif description from the readme:

Note that fteqtv is just a qtv proxy made by the fte team.
The thing works by transfering mvd files over tcp/ip. The result is a reliable buffered connection, providing smooth action. The tcp protocol is purly an mvd. You can connect with a simple tcp client and remotly record your own mvd from it.
