The InfoZip zip/unzip is fairly generous with their copyright conditions,
and they are fairly confident that they are not violating UniSys' or
PKWare's patents.

In practice the only problem I've seen is with the huge cumulative directory
that Zip files have at the end.  On the on side the unzip software needs the
directory for random access through the archive, on the other this makes 
things s..l..o..w when used with tape backup systems.
