Some Plugins

Mobcatcher:
Allow you to get mob spawn eggs legitimatly, this would be very helpfull and it works with 1.2.3.
All you have to do is (after making sure you have the right materials, which is by default 5 redstone dust) hold an egg (configurable) and left click on the mob you wish to capture.

Runecraft:
Would add to non-combat magic system, from what I hear its quite good and the developer is updating it this weekend or next.

Runecraft adds magic spells to the game which are triggered by block patterns called runes.
It let's you create teleporter and waypoint runes for instant travelling, build hidden doors into mountain walls or enchant your tools.

If I see any more cool/interesting ones I will post them in a reply. Just thought it would be nice to share!

The Mobcatcher plugin seems okay but doesn't seem overly needed. If it adds lag to the server I say a definite no.

This runes one seems interesting. I do like the idea of teleporting using magic. Gives it a better RP feel instead of just the random teleportation we have now. All the other features of it seem meh.

Mob catcher doesnt really cause lag, it just gets rid of a mob then gives you a spawn egg for that mob.

And I agree, some bits of runecraft are a bit odd, but others look amazing if you see some of their videos.

Runecraft works with 1.2.3 now
