Teleoperation/telepresence has been around for quite a while, and the it 
could be argued that the current Pathfinder mission is using a variant of 
this technique.

Whilst I agree that VRML is an interesting language in as much as it
is/will be the first genuine standard for VR, VRML enthusiasts should
be aware that just using the language is not a merit within itself. In
conferences I've organised or attended I've seen stacks of submissions
in which quite mundane applications which are being proposed as
significent simply because they have developed in VRML. In most cases,
similar applications have been around for a number of years using
traditional VR packages.

The example given above implies a dedicated, special purpose link
between the engineer and a highly specialised site. Why use VRML? What
advantages does that language bring that say, dVS, WTK or even
Superscape wouldn't?  Ingenious solutions to make VRML perform tasks
it is not well suited to may well be of benefit to the general VRML
community, but if an alternative software package would have bypassed
the problem, then it would be good engineering practice to use
it. Keep the VRML hacks for specialist VRML workshops.

VRML certainly does have its place. For generally distributed Internet
based applications, it will be essential. The free browsers and low
cost world creation software also makes it very attractive for
low-cost PC applications. But it is not a panacea. Instead of the
deluge of 'me too' VRML papers, I'd be very interested to see study of
what VRML *shouldn't* do!

Cheers,

Robin
