  We are currently conducting a comprehensive and consistent re-processing of
archival HST-NICMOS coronagraphic surveys using advanced PSF subtraction
methods, entitled the Archival Legacy Investigations of Circumstellar
Environments program (ALICE, HST/AR 12652). This virtual campaign of about 400
targets has already produced numerous new detections of previously unidentified
point sources and circumstellar structures. We present five newly spatially
resolved debris disks revealed in scattered light by our analysis of the
archival data. These images provide new views of material around young
solar-type stars at ages corresponding to the period of terrestrial planet
formation in our solar system. We have also detected several new candidate
substellar companions, for which there are ongoing followup campaigns (HST/WFC3
and VLT/SINFONI in ADI mode). Since the methods developed as part of ALICE are
directly applicable to future missions (JWST, AFTA coronagraph) we emphasize
the importance of devising optimal PSF subtraction methods for upcoming
coronagraphic imaging missions. We describe efforts in defining direct imaging
high-level science products (HLSP) standards that can be applicable to other
coronagraphic campaigns, including ground-based (e.g., Gemini Planet Imager),
and future space instruments (e.g., JWST). ALICE will deliver a first release
of HLSPs to the community through the MAST archive at STScI in 2014.
