Podcast fodder? Questions for Paul.

I Hope this is the right place for this post. While listening to the podcasts I wrote down a list of questions that I would love Paul's opinion on. I hadn't heard a podcast where he answers questions from one of the pod people in a while. I've listened to all the podcasts that were still available online or that I received in the big gob as a perk in the kickstarter for the world domination dvd. I don't think these topics were covered in any previous podcast, but my memory isn't what it used to be. Here my list:
Questions for Paul:

1. Is it ok to plant comfrey above the drain field of septic and use it for mulch around food crops or fruit trees. Are their other good plants for this.

2. What are your thoughts on large plastic tanks for rain catchment to supplement water input into a pond or natural swimming pool.

3. In a poly - cultured system do you recommend importing heirloom seeds for annual veggies like squash or other varieties to prevent hybrids.6. In order to make a good deer fence, is it a good idea to build a 2-3 ft hugle culture with a 6 ft fence on top around the perimeter of annual garden?

4. What is the differences between permaculture and biodynamic farming?

5. What is your opinion of slugo, organic slug control.(iron phosphate)

6. How to combat creeping butter cup in lawn

Thanks for all the you do

Permaculture is a system of ethical design for all aspects of human settlements which may or may not include biodynamic farming in food production, depending on the needs of the site and the goals of the designer.
