By the way, isn't the eSports broadcasting idea pretty ridiculous anyway? Not everybody can afford joining TT, WSBK or MotoGP, but almost anybody can get themselves a copy of GPB and start competing with other folks. What's the point in watching this as a broadcast when you could race yourself? Sounds like a waste of time and resources.
Well, I totally respect your point of view on that, but you also have to understand that there are people who do enjoy watching eSport events on online live streams too. 
Which makes me wondering what is it exactly that attracts them... I suppose that it's the element of a show. Maybe also the fact the eSports can be much more relatable to an average viewer. How are you going to achieve that with a bike sim? Just ask yourself. Realistically, how many viewers are going to watch a GP Bikes broadcast? How many will get out of their way, and not just click a curious YouTube link at their leisure, but will actually be waiting for the appointed time and will be watching you, guys, doing laps in GPB, rooting for someone in particular of whom they can only see the nickname.
Of course, the going of your local championships is important for you, because you are the participants. Also, you know each other pretty well (I, myself, was away from the forum for a long time, so many of the people here are new to me, and I have no intention to participate in anything but trackdays, hence "you" as opposed to "us"). But what the audience wants? Would Rossi have so many fans if the only things you could see of him were a nickname and liveries? Ok, maybe also an occasional shot in the studio and an obligatory interview.
If you want audience beyond the people of the special interest, you have to come up with something to appeal to them. And speaking from my experience being a simmer myself for a long time, I can say it's really hard to get people interested in hardcore simming. If at all possible...
All I would say is that like many sports I like to enjoy participating in myself, I also really enjoy watching them on TV too; are you telling me that you don't do the same?
I used to... But after getting a solid Internet connection I stopped seeing TV as anything more than just an annoyance. And I also stopped caring for following competitions. It's rather a waste to follow other people's lives when you have one of your own. At least, if you don't know them personally.
But at least watching RL stuff can be fun for one reason or for the other. Watching eSports? Well... I remember there was a record of a broadcast of two teams of DCS pilots flying missions against one another. That was the only thing I felt like I could actually be watching live. But then again, it still lacked something... After giving it a thought, if there was a real life competition like that, I'd rather watch that. Same with bikes, I'd rather go back to watching WSBK and MotoGP (not to mention TT).
Not everyone will be good enough to compete at the top events in live streamed eSport; does this mean they just won't be interested in watching eSport events they enjoy on a lesser basis? Same as I enjoy playing Tennis, but I know I'll never play at Wimbledon but I still avidly watch Wimbledon on TV.
You said that yourself. You don't watch people playing a tennis sim. You enjoy watching Wimbledon on TV. And if you have a choice of different real life motorcycling events, why in the world would you opt to choose watching GP Bikes instead? Of course, let's pretend you don't belong to the forum and have no attachment to the community... What would make you watch GPB over real life motosports?
That said, I think I have an idea what would make me watch it... If the winner would have a chance at a spot in an RL MotoGP team (or at least Moto2). But I have a vested interest

I want simulators to get rid of their "gaming" past and to be accepted as a full fledged training tool. Games are games, sims are sims.
Just because one doesn't actively participate in an event doesn't mean one won't be interested in watching an event on live-stream if your interested in the outcome or support a certain team or rider, surely?
For that, the one in question needs to develop a certain attachment to that team or rider first. With eSports and sims in particular, not sure how that is going to happen.
