Some time ago, I posted a Python script (needs python-netclient) that
performs a similar task to what Yaouh! did. Including updating the empty
files. Just search for "Yaouh! clone" or "fill_gaps" in the archives.

In the following weeks, I should have enough time to clean it up and add
the functionality some people requested - namely, updating also tiles with
lower zoom levels if one with higher was updated, and symlinking empty
tiles to one file.
