So basically, I'm making a mod that, among other things, will include two special blocks: A wireless button that is linked to a wireless redstone power source. Upon being placed, the player will receive the button, linked to the power source. Theoretically, pressing the button should result in the power source emitting a redstone signal, even if they're not connected. However, this doesn't work. Could somebody please help me with this?

Blocks are singletons. Any variable in them will be shared with all blocks, just like a static variable. So you can not save activated state in the Block directly. However, you can use a TileEntity to save the state, or better, block metadata.
