That's not remotely the same problem (see my other message - and indeed my 
original messages). If you have an open system, and don't care about 
security and correctness, then of course a registration scheme is far 
preferable. I'm paranoid enough that I'm not willing to allow anyone else to 
put code into the server without the extensive vetting of an Ada compiler. 
(This is one of the same reasons that I rarely make any of my code open 
source -- I don't trust anyone else near my code. Even with RRS, I always 
verify every change someone else makes before adding it to my personal 
copy -- I've saved a lot of wasted debugging time by doing that.)
