I wonder about Brian. Feels more like he is not understanding the issue.

Well, since I'm an RSX guy at heart, reading in the file in memory 
first, is pretty much never an option. :-)
And that said, the largest file blobs I'm serving from my RSX system 
over HTTP is roughly 500.000 blocks... So about 250 Megs. Now, if you 
want to suck that into memory before serving, then I will not stop you. 
But I should point out that there is pretty much no limit on how large 
files people might want to serve...

So you always needs to be prepared to deal with something bigger...
