In short:
1) law change for allowing bank account opening without physically coming to Estonia is in the government and should be in force by Autumn
2) our customers are successfully using different payment providers
3) LLC is the "de facto" incorporation type for our customers
4) Becoming an e-resident won't make you an Estonian tax resident, so you don't have to worry about your worldwide income. But when you start an Estonian company then the company finances/taxes have to be done by Estonian laws/rules.
5) Going to Estonia is like going to other European countries. You need transportation and a place to stay and you get them via normal means online :). Visa requirements depend on your real residency. Being an e-resident doesn't change this. For more info: http://www.visitestonia.com/en/
6) For physical coworking space, just google "coworking tallinn" or something similar. Should be plenty of spaces available. If you wan't to see the other end of Estonia, then "coworking tartu" :).
