Hi Radim, - (I know that OS people don't like to here it and they will argue that is is not a way ahead.) WCS is not widespread yet and there are various issues with implementation in UMN Mapserver (and other servers) and GDAL. Combination of that issues made it for example impossible to

Yes, requests must be somehow assigned to layers/providers so that progress may be emitted from the right place. It could be maybe done using GDALDatasetH pointer? Just another hack. I've no ideal solution for this. Your suggestion could be indeed a possibility : adding 2 methods

Hi, That sounds fantastic - looking forward to all these improvements! The WCS is one more OGC implementation that brings us closer to more complete GDI support. Personally I am excited about the composer improvements. Together with the serial printing initiative from the Atlas plugin we

Yes - Radim already made a first pass implementation using GDAL WCS though he said there were some problems with it - I think the most critical being that it doesn't support proxy access (I am speaking under correction here as I haven't looked into it in that much detail myself). This

Given the planned work on the composer I wonder if you're considering to move the print code (e.g. [1]) outside of the GUI/app control, and make it available for the python API, maybe in a QgsComposerPrinter class. This would also make Atlas simpler... giovanni [1]
