* Not available until MySQL 5 migration complete (Domas, what's the 
status on testing?)

* Collation use for sorting needs to be double-checked to confirm it 
wouldn't interfere with present uniqueness constraints

* Collations not available in MySQL for all languages

* Multilingual sites possibly not well served by table-wide 
language-specific coding

Doing our own localized sort key encoding and adding another indexed 
column to sort on would avoid some dependency issues but has its own 
deployment and maintenance difficulties.

It would also be possible to use a separate column for the collated 
sorting while using MySQL 4.1+'s native collations, if the uniqueness 
constraints are a problem, but this is still dependent on rolling out an 
upgrade from 4.0.
