Currently, the stylesheets as gzip compressed tar archive are 252 KB. I think it should be possible for the t...@h server to offer them as tarball if the SVN server is brought to its knees by our clients doing regular 'svn up's. But the problem remains that the server should be able to check the version (svn revision) of the styles used for rendering. The client should add this information to the meta data when it is uploading a tileset. If the server stores this information it could be used to trigger render requests when styles change.
