What is not nice is the code for the compressor, which is a total mess. I have been holding out on implementing LZMA on kernel.org, because just as zip (deflate) didn't become common in the Unix world until an encapsulation format that handles things expected in the Unix world, e.g. streaming, was created (gzip), I don't think LZMA is going to be widely used until there is an "lzip" which does the same thing. I actually started the work of adding LZMA support to gzip, but then realized it would be better if a new encapsulation format with proper 64-bit support everywhere was created.
It doesn't handle streaming?
So you can't do: tar c dirname | 7zip dirname.tar.7z ?
