Nominal base of the team is a long way down the globalisation priorities: Irish interest is in Dan Martin and Nick Roche, not Ceramica Flaminia, De Rosa or Colnago; UK coverage (apart from one channel, obviously) does not get excited about wins by Greg Henderson of EBH just because they are on a UK registered team.
In terms of competition for sponsorship money from large global companies, TV coverage globalisation is what will matter (even with the advent of Team Sky and Cavendish, TV and mass media coverage in the UK is minimal), and this is dependent not on registration of teams, nor on simple presence of riders (v few UK viewers tune in to see how Charlie Wegelius or Chris Froome are getting on), but on competitive riders featuring on races, or at least being expected to do so.
That will occur by investment in the continental tours, so that potentially very good athletes will consider becoming good riders, and they will then have a chance of being picked up by top teams early enough for them to have a career as stars, rather than joining at an age and with an experience base that means they will only ever be domestiques if they do join the larger teams.
