Sorry. Denial doesn't help. It's not only "possible", it's being done
all the time. Cf. <http://www.saout.de/tikiwiki/tiki-index.php?page=LUKS>,
for example. But you are attacking a strawman anyway.

Client-side decryption matches much better what you had in mind -- and
I think it's provably no less secure (and more convenient).

The only hypothetical advantage of server-side encryption (there might
be an opportunity of indexing) seems to be so mired in technical
difficulties (if you want to avoid information leaks anyway) that I
can't even imagine whether it's a real advantage.
