Next beta release of SevenZipSharp.
Added web streaming support for SevenZipExtractor (particularly simple ConnectStreams) and stream policies (CanSeek/CanRead/CanWrite).
Extracting a 7zip archive directly from web will cost you twice as more traffic due to the architecture of the native archiver. It is recommended only to read file table and properties, and convert ConnectStream to MemoryStream to use it within SevenZipExtractor.
To Windows XP SP2,3 and Vista users:
as usual, do not forget to unblock SevenZipDoc.chm if you want to view it (you can do it in the Properties window of this file).
