Hi Ric,
You never say what you are practicing, but it seems to me that your situation could be made to work. A couple of pieces of advice though ... You will undoubtedly be told that some things you are doing are wrong and to change them. Do your best to do just that. Whenever anyone from your group can make the trip for training, be sure that they tape the entire training session. This way you can all see the corrections and advice that are given. Thank the instructor for going to the time and trouble to help you. The vast majority of decent instructors in the Japanese Sword Arts teach for various reasons of their own, not to make a living. It is a large pain to try and teach a group long distance, and the fact that he is willing to help says a lot about the gentleman. A small gift for his help is entirely traditional, and would probably be in order.
Cheers,
Paul Smith
