Actually, the "monster.machine enblend " part of the
above command must be given as enblend arguments, else hugin will fail to
execute the ssh command. This is because hugin quotes the executable name to
allow enblend to be located in a directory with spaces in its pathname.

Well, cygwin contains an ssh-server that integrates nicely into windows :)

Unfortunately not. However, the current code could be optimized a lot more, its
a stupid, straightforward implementation of normalized cross correlation.
