Hi,

I think that is a great idea if we can find code that is suitably licensed. The 
code that detects the .gz is in src/base/output.cc; look for 
OutputFile<gzofstream> being instantiated. The code that is actually doing the 
compression is in ext/iostream3.We’d need a streambuf class that wraps LZMA
