Questions about Logistics pipes

[rebuke]

So after fiddling with logistics pipes, I have a few questions:

1. Is there a way to make a network draw from more than two sources of the same material? If I have two sources of redstone, one at the front of my network and one at the back, even the crafting at the back insists on using the source at the front.

2. Is there any way to have a chest with both a supplier and provider pipe on it that doesn't loop itself or overflow? For example: I want to keep a chest of coal dust and copper wires that resupplies itself for my H.V. solar panel crafting system but if I want that chest to be accessible I have to put a provider pipe on it and it starts supplying from itself, getting nowhere. I have tried using chasis pipes but the supplier module doesn't work quite the same.

3. When I use Mk. 2 crafting tables it seems that they don't recognize that they have items in them and don't use the supplies in them to craft... I only have them attached to a crafting pipe that is configured. Am I doing something wrong or are they bugged?

4. If Mk. 2 crafting is bugged is there a good way to duplicated it in a space efficient manner?

Thanks in advance.

I can't help you for 1 or 2, but I'm pretty sure your problem with 3 and 4 is that those are meant for use with RedPower, not BuildCraft. You use those by putting a transposer on top of them facing down, and each time the transposer activates, it crafts one item. You'll have to use the regular crafting table (possibly with satellite pipes) for now.
