[Haskell-cafe] Self updating binary

Hi there, Has anyone experience suggestions with writing self updating binaries for windows ? I have a small utility that I have to install on two "unmanaged" pc's, I would like to let the program check an url, for new versions, download a new versions, some how check that the program is valid (with a build in key, or certificate) and replace itself when necessary. Has anyone already done this in Haskell? Any suggestions, links ? Thanks, Pieter -- Pieter Laeremans pieter@laeremans.org
