Basically the webinar was a decent overview of ACA and the practitioner (more individual needs than business, but overall good).
The BIG take-a-ways (for me) were when I reviewed the forms mentioned. The 8962 (reconciliation) and the 1095-A (reportable from the "Market Place") helped somewhat with the review of the 8965 (exemption forms) having the biggest impact with the most information.
As with most government instructions, you have to take-it-slow and wade through step-by-step but in this case very worth it. With all the examples and some thought, you can come away with a decent understanding of the practitioner needs for the coming tax season (as least as to the individual side of the ACA reporting for 2014). This might also offer a partial answer for your clients questions on what they might require as to forms, etc..
