Hi Marc,
ACME is progressing, although not as fast as we would like. We had a large unexpected hurdle to overcome the last couple weeks and we are now back on track. Thanks for pointing out the coming soon page. The plan is to replace it with our new EE2 website but every time I try to launch it I run into another bug either with EE2 or third party modules. With fingers crossed we will have the site ready this week and people can start registering for the beta program.
In regards to ACME’s layered core structure, it will work just like any third party module for EE with the EE addon installed. The only difference is that it will also allow for advanced features for programmers and enterprise customers. We will be explaining in detail ACME’s structure once the site is ready.
We appreciate everyones patience, no one would like to release ACME CART more then myself
