yes,  http://download.osgeo.org/livedvd/data/live_data.README

This dir is to hold data samples used in building the LiveDVD.

It is not appropriate to hold large binary files in SVN.
Subversion is a *source code management* tool (SCM), not
a data warehouse. Due to the history and undo features
of SVN, once checked in a binary file forever takes up
space in the back-end database, even if you later remove
the file.

Also downloading datasets from 3rd party websites have
a nasty habit of going stale after a few months.

So here we are. Contact the live-demo OSGeo mailing list
to get a file posted.

Uploaders please make sure that all files are set to be group-writable
and world-readable.

For more general needs see the OSGeo geodata project & server space:

unfortunately since svn is all about preserving history, now
that it has been uploaded to svn it is always going to take up
that space in the database/backups, even after we move the file
to a more appropriate home.

before agreeing to upload to the download server, I'd ask about
the 64mb dataset and if there's a lighter version available?
Space is tight on the DVD.
