Dear Mr. Ripley,
snowfall 1.7 is finished, and is now working on Windows as intended -
sorry for my oversight of that error. The given example now runs (as a
sidenote: snow does not have to loaded explicitely, snowfall will do that).
Also the NWS startup is fixed now (thanks to M. Schmidtberger for a
small patch) and an error in sfSapply is fixed.
Otherwise minor things were corrected or added.
I uploaded the package to CRAN yesterday and beside it is downloadable
from our site http://www.imbi.uni-freiburg.de/parallel
Greetings, Jochen Knaus
