  I think it would be hard to code and very time-consuming: you would
have to cast many new rays for each incoming ray, average them and take
this average as a parameter for the colour of your frosted glass. Of course,
you could keep some things in memory, but it then comes close to radiosity.
Maybe a modification in the radiosity code could do it?

  Anyway, why not?
