If you're using C++, then this is already done for you in tif_stream.C. I 
believe it's turned off right now by default in the build system due to ABI 
issues. So if you compile libtiff with it enabled, you can then run create a 
ostrstream our of your buffer which you then pass to TIFFStreamOpen().
