Is there a way to stop players being able to see the level seed in Minecraft SMP 1.8 when they press F3? Because they could use this seed to generate a copy of the world and then find the location of strongholds, dungeons, ores etc.

OptiFine has, among many other improvements, a clear water option (under Video Options -> Details). This is a pure client modification and works just as fine in SMP. (Note that this is not compatible with MCPatcher, which is however not needed since OptiFine also includes HD texture support).
MobLocator
Due to there not being any plugin that currently does this, I have developed one.
It is called MobLocator and can be download here.
/moblocshows the number of each type of mobs that are present in the world./mobloc [mobType]shows the location of the 10 closest mobs of type mobType. (Using euclidean distance). Note, you can use a mobType of all.
Feedback welcome.
Edit: Updated link to version 1.0.6, I forgot squid.

While I doubt you can do much to change the client that people use to connect to your server, here's my terribly convoluted solution:
Explore a great deal of the map to force it to be generated then edit the seed in the
level.datfile. It should report what the current seed is (which will only do anything when they go further out than you did...and there might be a huge discontinuity when you do).
