Mirror questions (they are in CVS, I have question though)

[A8hm]

With the mirrors is it possible to make hall of mirrors (please say yes!). Will the amount of times a mirror is allowed to reflect another mirror be set in a c_var so that people with slower rigs could set it to maybe 1 or 2 and people with great rigs could set it to 100 and get the true hall of mirror effect?
Will the creation of semi-mirror surfaces be possible like polished marble?

Also will you also create a way to make camaras and videoscreen (render to texture) this release? That will assist in modern and techno maps.
