FIA rules "bend" for Ferrari
Although the original regulations for 2008 stated that Formula One teams can supply just one other squad, Ferrari have received permission from the World Motor Sport Council to continue to supply two teams with its customer engines for the 2008 and 2009 championships.
The two teams that Ferrari will supply next season are Toro Rosso that swapped to Ferrari power in 2007, after they had used rev-limited V10 units from Cosworth in 2006, and Spyker.
I wonder if the same permission will be received also by other teams that would like to help more than one Formula 1 team.
