Streams (including Mikogo, TeamViewer, etc.) - technical aspects.

Yeah, Heroes of Might and Magic III at WCG or ESWC, or even at large LAN events – that would be interesting, in my opinion, but it's unlikely because WCG lasts a maximum of 3-4 days, and I think there would be at least as many people wanting to come and participate as there were in Warcraft 3 in 2003-2005 (8 groups of 7-8 people). It would probably be impossible to play that many games in 4 days.
However, on the other hand, broadcasting matches of top players would be profitable from a financial point of view – I think there would be a lot of interest, and the audience would be huge; how much money could be earned from advertising during breaks in a 3-4 hour broadcast? :)

------------- Only, could the first week have turns made like in an RTS? ----------------
By the way, is it even possible to implement this for money? (I think many people would be willing to contribute financially to this).
