OK, right tools for the job - 

Personally - I wouldn't use WooCommerce for this at all.

For what you are describing I would use WPeStore and WPeMember.  No integrations needed and no conflicts with Thesis 2.1.

You can have a lifetime access to both for less than half of the Woo subscription license and WPeStore is still best in class for managing digital downloads and subscriptions.

This meets all of your criteria easily with Thesis.  Except for courseware.

I am currently building courseware sites with 3 systems; Sensei, WP CourseWare, LearnDash.  At the moment Sensei is my least favorite of them but I'm not yet ready to make a final analysis.

Currently Sensei relies on a template system that will require an integration plugin to work with Thesis.

WP Courseware and LearnDash work fine out of the box.

A Woo centric solution to this will be the most expensive and most complicated system - expense and complication without any benefits.

Ummm... the suggestion I gave you was based on the earlier criteria.

WP eMember's "drip" facility is too complicated to be worthwhile, yes a member can have multiple concurrent memberships, no prorated charges or 1 ckick upsells.

It sounds to me like you need to do a bunch of decision making and research before you can choose a system.  That said, a woo based system is going to be the least feature rich and the most expensive.

Take a look at WPMU Dev's membership plugin.

My favorite forum is this one - Simple:Press forum

You're welcome - good luck with the project.

Yes, I haven't released it publicly but I'll email a copy of it to you.

BYOBWebsite now uses WooCommerce to process transactions, WC Subsctiptions to manage the subscription process and my own roll your own plugin to manage user access.

I built and manage a site that uses WC, WCS and WC Membership.

So my advice is based on this experience....

1) My opinion of WooCommerce as a membership system hasn't changed, primarily because WC Membership is such a green plugin.  I had to write a Thesis Box to make it work in an acceptable way on my client's site.  It is PRIMARILY designed to allow you to create a membership store, where members can purchase products at a discount.  Otherwise the authors appear to know nothing about the needs of membership sites that restrict access to content based on payment of a fee.

2) Their support is non-existent.  I had hoped that would change with the sale to Automatic but it hasn't.  They tell you that they hope to respond to your support request within 7 days.  I went more than 30 days to get a response the last time I needed help (early this summer).  Needles to say that you need to be able to figure this out on your own or to be able to find support elsewhere.

That being said - I made the choice based on my desire to integrate it with Infusion Soft.  I don't regret that decision, I just know not to count on support.

No one has good answers on CSV import.  The only way to really succeed at it is trial and error.  If you have 100 records or less forget about importing and take the time to enter the data manually.

In my most recent experience - that is in the last 18 months, Wishlist Member support has been the best of the tools I've used.  

I'm told that Digital Access Pass support is phenomenal.  Unfortunately they have a relatively complicated non-WordPress system which I think gets in the way of using it with other WordPress plugins.
