Yes, you will just have to edit your gnunetd.conf file to allow access from 
the client IP (or subnet).  Also, you need to configure the client 
(gnunet.conf) to talk to a gnunetd daemon on the server (replacing localhost 
with the remote IP).

The GTK interface does not have an options dialog, you need to use 
gnunet-setup or edit gnunet.conf (~/.gnunet/gnunet.conf) by hand for the 
remote connection.

No.

Yes. But you cannot tell if it is happening or not.

The account can be removed, the files will stay indexed as long as they are 
accessible by the user running gnunetd and are not moved.

I suspect what you want is to do a search for
"Turbo AND man", that should work (but I do not test this feature very often, 
there are some pending feature requests on Mantis for making the search 
nicer/more intuitive to use).

You will get results for anything that was uploaded under the given keyword.  
There is currently no good way for GNUnet to prevent abuse of keywords.

You can index directories recursively (will happen automatically), but 
add/delete changes are not yet supported.  This is another feature which is 
already filed on Mantis and which will be worked on once we have the time to 
do it.

There is the -K (--global-key) option.  Also, you do not want to use "-D" if 
you want LE-generated keywords for individual files.

Namespace/directory update intervals do not imply that GNUnet will 
automatically re-run the insert command as necessary for you (at this point).  
Again, these are issues that would probably fall under the "cleanup the 
publication process" Mantis feature request.

Both sporadic and interval mean that you must do it manual at this point.  The 
difference is for the receiver: should  he expect periodic updates, or should 
the receiver expect updates to happen on an irregular basis.  Admittedly, 
this is confusing and one of the things that will need fixing once namespace 
support is added back to gnunet-gtk.

Old releases will always continue to be reachable.  The GNUnet client is just 
instructed to look for updates.

The "-N" option lets the uploader determine the ID for the next version of the 
collection.  Otherwise, GNUnet will pick a random ID for you. Again, I'm 
aware that these things are not yet really usable, needing both better 
implementation, better UI and better documentation.

Oh, my answer about the "-D" option is for 0.7.1 (IIRC the option has the 
inverse meaning in 0.7.0e).

I hope this helps a bit ;-)
