Thanks, Even. I will take a look. I suppose I could read the stream into
memory, and then read from that.
Will vsistdin work on windows?

In the general case, no. If the file has been specifically created for being read in a streamble way and the read access pattern is compatible of it, yes. You may read with interest the "Streaming operations" section at the end of
http://gdal.org/frmt_gtiff.html for more details
The GDAL /vsistdin/ special file mentionned in it is mostly a wrapper over standard stdin, with buffering of the first 1MB so that all seeking within this first MB works. Beyond /vsistdin/, only accepts dummy seeks (no actual position change), or forward seeks.
