We're not talking about a server-wide setting here, we're talking about a 
per-process setting. You really believe any of those apps you talked about 
will ever have 524,288 files open at once? And then multiply that by multiple 
processes? Do you have any idea how much kernel memory it requires just to 
have that many file buffers?
