I spent some time trying to write an extension to do perspective transforms a while back and I failed. The result of that experiment is in the Effects menu (labeled either "Summer's Night" or "Envelope"). The envelope effect is not a true perspective distortion. If you would be interested in helping me with the math (I've still got the code for my two or three other failed attempts around somewhere), maybe we could get something clunky worked out in python.
FWIW, here is the persp transform code in AGG
