As bandwidth increases it is possible to deliver very sophisticated learning experiences through on-line technology. However, most users do not yet have the equipment needed to benefit from this kind of application. As a result, most complex on-line simulations have to occur in some kind of special training context or lab.

There are several companies offering custom-made or "off the shelf" simulations of this kind for those who have the resources to pay and this is an area in which we can expect to see massive developments as technology improves and design and operational costs fall.
