Maui is changing fast. There's quite a bit of construction going on, and wonderfully it isn't all dedicated to resorts and condos. Tourism will probably always be part of the local equation but some businesses are starting to use those tourist dollars to build more sustainable businesses (e.g. Maui Brewing Company, Ocean Vodka, Maui Built, etc.). What I hope to have happen is to have that growth channeled into making Maui more friendly to developers such as yourself. Things such as more banking geared to handle businesses, more/better funding of schools, some "affordable" housing that isn't surrounded by timeshares, co-working spaces, more knowledge sharing opportunities (conferences, informal networks, etc), and of course attracting talented people who can leverage all of this to build some great stuff.
Where X coud be boat/yacht/helicopter/whatever?
I am surviving well as a developer, living off the grid, with a satellite internet connection.
What we're still lacking is good jobs, and access to VC funding for companies we want to build. mbloom is not the fund that we need to grow our tech industry, if anything it's looking like it'll poison the waters.
