back-seeking may be needed for more complex operations in ZipArchive,
but to read 
a stream directly from the Zip archive, it's not required.

For instance, there is a Java Zip Input Stream, which is buffered but
not seeking.

it does support non file system, but the file system must be seekable,
which is 
not the case for http.

Description:
------------
zip:// stream wrapper doesn't support streams created from sources other
than 
files. E.g. reading from zip://http://example.com/file.zip
will fail
with

Warning: 

As far as I can see, this is just not implemented in ZipArchive.

Test script:
---------------
$res = fopen('zip://http://example.com/file.zip');

Expected result:
----------------
Reading from zip wrapped URL should be possible.

Actual result:
--------------
Reading from zip wrapped URL gives warning:

fopen(zip://http://example.com/file.zip): failed to open
stream:
operation failed
