I have been experimenting with delivering a version of the business architecture course at a distance. The issue has always been that when individuals want to enrol there are never enough at the same time to make a course economic for delgates and the trainer alike.
So by offering a version of 121 seminars and material on an learning management system it means the problem can be solved.
I have mentored one client recently and it seems to be well received. Skype as a delivery method is a bit flaky though with screen control freezing to much but as a first try all is going well. The delegate is based over 250 miles away and that fact alone proves the concept.
