Sorry, ADIOS has already been used (and I think copyrighted).  [Company 
Name deleted] developed an access method (ISAM) for IBM mainframes 
running OS/MVT, OS/MVS, etc. called ADIOS (acronym for "Another Disk I/O
System").  It was coded in assembler and accessed from COBOL or assembler
as callable functions, and outperforms the "standard" stuff by a mile.

Plus, the terminal i/o control portion of the in-house ADIOS-based realtime
system was named TACOS ("Terminal and Communications Operating System", I
think).

Please, no anti-IBM, anti-COBOL, mainframe-bashing, etc. flames here.  
Mainframes are not necessarily evil (or, is that "necessary evil"? :-]).

And, no "too late for April Fool's Day" comments -- this is a true story.
Only the names were changed to protect the innocent.
