A future-proof way to list what facades are on a block, and which sides they're on, would be helpful.

@planetguy32 - generally, my plan was to:
a) split off IPipeTile into IPluggableProvider and IPipeTile
b) add IFacadePluggable which gives you that information

Would this work?

(Also, BuildCraft will automatically not do redundant facades twice, so just register anything you need)

For what you're doing, I think a14eb3b is enough

(Yes, it does let you define custom IFacadePluggables, both with and without a custom renderer)

That looks perfect, thanks. I've finished writing my end of this, and it's working.

Excellent. Closing. However, don't expect a release before February.

Good to know. I'll add a check for the actual API I use, and make sure to test it with other BC versions.
