I display the tiles with pymap (which in in the svn [1]), but I extended
that script a little bit, so that it can handle the t...@h-tilesets (zip-files)
directly.

Can you send your extension?
Here it is (as attachment).
To use ist, you have to install the attached file parallel to the
original pymap-file. Create a directory tiles/osma.zip additionally to
the existing tiles/osma. Then you can put your created tilesets into the
osma.zip dir.
If you have a connection to the internet, then you can populate the
other dirs in tiles with the original pymap (for instance for
mapnik-tiles or the lowzoom t...@h-tiles).
My pymap-zip won't connect to the internet at all. It serves only the
pre-fetched tiles or tiles from a tileset-file.
You can put your own slippymap application into the dir planer. To
display it, you have to enter the URI http://localhost:8008/index.html
(or http://localhost:8008/planer/index.html if you installed an own
slippy map) into your browser.
