As to my second point, the fact that you can drive electronically to that lawyer's office and the lawyer can respond electronically from that lawyer's office is basically the equivalent of me standing on the IL side of the Mississippi River with a megaphone yelling legal advice to someone across the river in Missouri. I am still in Illinois. That is, it is where the lawyer is, not where the client is. Now, if I wasn't licensed in Missouri (I am) yet went across that river and set up office in downtown St. Louis and started accepting money for filing legal papers in Missouri courts, that would be a different matter. Even then, I could probably do it so long as I got admitted pro hac vice in each case.
Another point, charges of unauthorized practice of law are a state disciplinary matter and do not generally have any legal implications in the particular matter, except for motions for sanctions or motions for substitution of counsel.
