yes they could be distributed separately. The DBMS could be useful as  
an alternative to a more traditional SQL DB; to avoid locking and  
address concurrency. The layer it provides is basically an networked  
hashed k/v store backed by BDB; but any ad-hoc b-tree/hash/mmap DB  
could be attached.

to implement the Redland BDB or libb networked storage ?

alternative, as simple k/w store for cached results/queries (non RDF  
necessary); or provide a nice RDF layer on top of it to manage the  
actual DBMS as a virtual (even though limited) triple hashed store  
( this also relates to our internal graph/indexing model too)...
