LZO (Lempel-Ziv-Oberhuemer) sounds like a candidate.

http://wildsau.idv.uni-linz.ac.at/mfx/lzo.html

It is a realtime compressor, designed for real time
compression/decompression of data.
It is really fast, like >20 Mb/s decompressions are easily possible and has
a pretty good compression ratio,
almost as good as gzip, since it favours speed over ratio.

It seems to have a pretty safe and compatible license.

It comes with a gzip cmdline compatible program called lzop.

I really love it.
