Probably PermissionDenied, FileExists, ConnectionReset also make sense.

Perhaps you can use SimpleHttpServer for your tests.  Oh, and since http
does support PUT, maybe you should say "http PUT is not supported"
instead of "http does not support put" :-)

That is my point.  If we auto-decode all control files, we'll be handing
a unicode-producing file to ElementTree when we try to get inventory.  I
don't know what ElementTree will do.  The docs don't say how it decodes
data, so I'd assume it will decode a well-formed Windows-1252 XML file,
as long as the file has an encoding declaration.  But if you're handing
it unicode data, will it try to re-decode it?

In terms of output, ElementTree defaults to ascii, but Martin's wrapper
changes that to utf-8.

Cool.
