This is a very interesting approach. I hope this is not a silly question and i dont know how to implement a GDLA driver, but i wonder if this approach is able to handle concurrent simultaneously read/write access to multi band maps? How would such a driver look like? Direct read and write access to the existing grass raster file structure or the design of a new raster file format? Maybe we can reuse an existing driver?
