Not appreciably difficult: pretty much every halfway respectable archiver on 
the planet lets you break up archives across multiple media.  Heck, even 
Microsoft .CAB files support this.  Also, don't discount thumb drives: I've 
seen 64Gb ones at reasonable price points and I'm sure larger ones are on the 
way.

There are really only two options here: redundancy or uniqueness.  If there's 
only one canonical record of each key then it becomes trivial to remove keys 
from the network: just take down the keyserver (either through legal threats or 
extralegal actions like DDoS, etc.).

If each keyserver has its own record, these hijinks quickly become impractical: 
if your given keyserver goes down then you just move on to another keyserver.

Given that neither hard drive space, bandwidth, nor physical media is a 
limiting factor... why should we strike redundancy?
