Probably my english are very bad, but i mean exactly that.

Never minded about proxies. Right.

+ WSH, as stated in this list, have poor performance and limited
 features when downloading

+ WSH, as stated again here, have no hash function, any hash algorithm
 have to be implemented in pure WSH or relay on an external script

So seems reasonable to, optionally, relay on an external script; seems
reasonable, because we can relay on an external script, to add the
'md5' field to <download /> tag, that the internal WSH downloaded
ignore but can be passed, optionally, to the external script.


You are right, we can just use existing <install /> and <update />
tags to do so, but the <download /> tag just exist, and i think is
more cleaner to use it.


[ Indeed, this have nothing to do with my ''server side download'' script,
  using the global /noDownlaod switch on wpkg.js.
  Clearly, also my script can be easily extended to use md5 hashes... ]
