Motivation for people with disabilities

A product like this could act as a great motivation aid for people with disabilities to exercise. After spending some time with my brother who has MS and who exercises (infrequently) on an exercise bike, alone and at home, when I left him I was thinking about how to motivate him. There is evidence to show that people are much more likely to exercise if they are with someone else or in a group. The idea of a multi user VR cycle group occurred to me and hey presto I came across this website. I can imagine an application like this could benefit many people with disability who would otherwise exercise alone.
