It is unclear to me what is the problem here. The settings variable 
ISABELLE_COMPONENT_REPOSITORY points to 
http://isabelle.in.tum.de/components by default, but that may be changed 
in $ISABELLE_HOME_USER/etc/settings in the usual way.

The remaining task is to maintain a complete mirror of 
http://isabelle.in.tum.de/components (which is presently at 12GB total). 
Some rsync setup should to the job, although we don't have that on the 
standard Isabelle rsyncd, as far as I can see. It should be possible to 
rsync via ssh for anyone who has access to TUM.

Note that /home/isabelle/components contains a few non-world-readable 
files that are not accessible via HTTP and are not meant to be published, 
due to odd licenses of the tools in question.
