I think it's a great idea.
This service should get people closer to destinations. For example on a Dublin to Galway flight your biggest headache is the airports. Getting rid of this requirement would save a relatively large amount of time, stress and money. Then on top of that you have the novelty factor from folks here and tourists. Plus it has the backing of a company already offering this service which comes with expertise, cash etc. and they wouldn't do it if they expected it to fail!
Good on them, looking forward to seeing this in operation.
