Did you know you can have >1000 different looking blocks in 1.7.x or lower only with Optifine installed? Also if you did know: Now there is a plugin (by me xD) which allows you to use the blocks in survival as well and craft them with fair recipes. You can see the recipes ingame via /recipes.
The Conquest pack is the default Resourcepack for the plugin, but it can be changed, so you can use other extended Resourcepacks as well.
I used this plugin on my own server Hardcore City RPG before.

This was all used on a server I played on. I think we used our own recipes though. It made for some really cool and interesting towns and builds.

+Dayne Close yes the client only needs Optifine and the resourcepack
So it's like a server side Quadrum?
