All the talk about obfuscation and the appearance of security...
Maybe someone could write a converter from our clear text format to the
Whitespace language...
then it would be really clear. It would give a whole new meaning to this
tread's subject "view source".

it wouldnt matter.. in that case one could simply program a rule to
take that case into considreation

and by moving to an XML based language it actually becomes easier!

short of createVRMLFromUrl('/cgi-bin/foo.pl') or some dynamic build
of the world
and even in that case it is possible if you want it bad enough
through tools like lynx... even though its a text only browser you
can do something like this {psuedo code}

$>lynx --source site.com/cgi-bin/foo.pl>>mysourcedworld.wrl

i hope you realise im not arguing here.. just presenting cases!

I was referring to delivering the data to the world as requested
and inserting it into the world via createVrmlFromUrl. It does
not make it impossible, just more difficult.
