Folks, I have extended Even's /vsigzip/ driver in trunk to support writing as well as reading. This means it is possible to write a file in compressed format by using a filename like /vsigzip/out.asc.gz. Note that the /vsigzip/ write driver does not support seeking around in the output stream so only output drivers that use VSI*L *and* that do not do seeks will work. So it can't be used for GeoTIFF, but can be used for formats like AAIGRID.
I implemented this primarily so that the new R driver could directly create a compressed object file.
