8.1) Can i use other wais clients to query a freeWAIS-sf server?

    Yes, all clients running the wais protocol (z39.50 V1 + adds) can 
    query an freeWAIS-sf server. 

    There is only one small incompatibility, which can be enabled 
    during installation of freeWAIS-sf (default is: run compatible). 
    This modification only applies to the document type URL and allows 
    to customize the headline. The original handling uses the headline 
    to store the URL. The modified freeWAIS-sf puts the URL in the 
    document id field. But this handling currently is only supported by 
    SFgate.
