And how about instead of abusing cookies for something they weren't
made to do, doing the following:
<div id="here-is-all-my-nifty-positional-data" style="display:none;">
...
</div>
• No cookie abuse (that's not what they're there for, they were made
for persisting data across requests and site visits, not for passing
in data)
• No 3KB data limit
• Same behavior
• In case it matters: indexable by google and other search engines
