You could take your chances on the dyes with optical media.  Some say
that in a proper controlled environment, they will last much longer. 
The best media I think are the ones from Japan and singapore.  There are
several places in Japan that now ship to the US for reasonable rates.  I
just ordered from 1 on ebay.  I think the reality is that nothing lasts
forever.  Optical media is probably much more likely to survive ICBM's,
but then you may not have a drive to read them...
