    Here is the current version of the abstract, in text:

    We propose a proven and efficient approach to obtain a new sample of z>1
    dust-free Type Ia supernovae. The resulting dark energy measurements
    from this sample of SNe do not suffer from the major systematic
    uncertainty at these redshifts, that of the extinction correction with a
    prior. By targeting massive galaxy clusters at z>1, we obtain a
    five-times higer efficiency in detection of Type Ia supernovae in
    elliptical galaxies, providing a well-understood host galaxy
    environment. These same deep cluster images then also yield findamental
    calibrations required for future weak lensing and Sunyaev-Zel'dovich
    measurements of dark energy, as well as an enitre program of cluster
    studies. The data will make possible a factor of two improvement on
    supernova constraints on dark energy time variation, and much larger
    improvement in systematic uncertainty. They will provide both a cluster
    dataset and a SN Ia data set that will be a longstanding scientific
    resource.

    All but the first sentence is copied from last year's abstract and needs
    to be updated.
