No offense Catalancs, but I think you lack imagination
With 10k licensed players, France can now support 2 teams in SL. There is one Welsh it makes 3 teams in 2012.
The RFL aims for an Irish team sooner or later, and a Scottish team to follow. It would make 5 non English teams.
Adding one French would not be a problem toward 2015. It would make 6 within the next 10 years, and that would be a fully European competition (3 French teams is I think the minimum to get French media fully involved).
It may not work, but we are far from naive dreams. The result of the poll talks for it anyway. Forum participants are very knowledgeable about the game. There would not be 2/3 of them for the idea if it was completely ludicrous.
On a final note, and this is, I admit, a dream, I'd find it great if at some point in the future there could be a Barcelona team in the competition...
