CDL names are only scoped to the current deployment. You want to talk to 
something outside it, you need help, which could include components that 
do directory lookups. Very high on my todo list is to do some bridging 
between JNDI and the HP smartfrog/cddlm runtime, so that deployed stuff 
can access the graph of deployed components as if it were a JNDI 
directory tree. That's just so that you can design libraries that are 
fully decoupled from any particular deployment framework -all they need 
to know is the jndi URL to get their configuration. I think I will stop 
there; LDAP scares me.

If what you are deploying is aware of stuff like OGSA--DAI, ByteIO, etc, 
you dont need all the file staging stuff, because it can talk direct to 
the services. What will still need is consistent configuration of things 
across your deployment, so different stuff running on different boxes 
all get the same pointers to the same remote data sources to work with. 
normal, non-lazy CDL bindings can share that kind of static information.
