*nod*  This works fine.  I have a secondary Clam instance set up to use 
only a selection of third-party signatures that I do not absolutely 
trust as hard black/white tests, which is called from SpamAssassin and 
scored based on the resulting signature names.

clamd will use whatever database files are in its database directory. 
It does NOT use anything in any subdirectories.

clamscan will use those, or:

1) whatever database files are in the directory you specify with the -d 
argument, or

2) whatever single database file you specify with the -d argument

The only constant is that there must be at least one signature database, 
even if it's a trivial hash database with one signature that matches on 
an empty file.
