It's not a worst case for me, it's actual case! And it's likely to be the
most-visited page on the site...

I realise this is not your average use of WordPress, but if the user data
could be cached in one swipe that would be a big help.

Luckily the site is unlikely to see very high traffic so I'm confident our
server can cope fine, but obviously saving 100 db queries would be nice!

Thanks for your time,
