For #1, there's youtube or just sending the replay to their friends. For #2, I really think this would be niche profitable but would require the most polish and time because pro teams would probably want to jointly visualize responses to specific timings and save their annotations as a type of historical team-lore, but it would have to be a tight and stable. For #3, (larger?) tournaments often have 2 game casters and it would be interesting to see different observations while still listening to a unified audio stream. What annoyed me the most when watching VODs or Twitch.tv casted replays is when the casters completely miss covering a multi-prong attack even though I can see something happening in the mini-map (e.g. all-in distraction + main/expo/expo drops). Some casters are good and rewind to look at the action from a different POV, but it's still annoying and gets in the way of a smooth casting flow. As a tangent, I wouldn't mind (far into the future) the ability to watch a web replay synced to a (pre-recorded) caster of my choice and play with the observer controls and POV while listening. In essence, that would require re-creating the realtime replay UI which is probably not feasible (but a former SCBW addict can dream). For #4, killer feature. Ads ads ads, or strike 'service streaming' deals with mobile carriers so people can subscribe to your streaming channel and pay $1/mo for the privilege of watching SC2 replays on their mobiles. For #5, there's some competition here like Twitch.tv, livestreaming, YouTube or VOD players, but ultimately you're right -- if people can watch synchronized web replays from multiple POVs and mob comment it should be enough to get decent attention. None of the other options allow for web interaction -- they're all modeled on TV audiences and distribution (i.e. faceless, delayed-alternative-channel-interactions). The closest is live-streaming where you can comment in the chat room while the player is playing the game, but: A) there's usually no record of your conversation to ROFL/analyze later; B) as the viewer, you have little say in which replay or game you want to watch next.
