I can think of two ways of doing this.  

We have touched on the Webservice component as a proxy
once or twice already.   An Executable Object Dataset
is created, registered and stored in the Cluster in
the normal manner.  That components function, however,
is limited to opening a link to another server outside
of the Cluster and passing requests and responces back
and forth with the general net.  The data remains
private, and the real server is also masked.

The other approach was also mentioned real early on. 
A service can be registered and flagged so that it can
be requested only when the owners LDS is online.  This
may make sense for 'Passport' like things such as site
passwords and credit card transactions. This creates
the possibility that the data can then be drawn
directly from the users node and not stored in the
Cluster Repository, in effect a sole-source server
connected directly to the Cluster, not a remote one
like the first example.

However, this opens a large breach in the sandbox. 
The LDS would need to be able to touch files other
than the Repository archive and any configuration
files we end up needing.

Yup.  There are many possible configurations and uses.
