With the owned licenses, are they lifetime updates?
Also, couldn't find any mention on the site about PA-DSS Compliance. Authorize.net is a REQUIREMENT for anyone these days - but on the roadmap it has no projected dates for completion. Potential dates would be handy especially in evaluation mode.

I took a quick run through the demo provided, but I found it quite complicated to get through. Not being able to adjust the size of those tiny windows on a 24" monitor makes it difficult to read. Also, couldn't find any way to setup dedicated servers etc

I think it's a nice start, but for $349.95, it has a ways to go to be competitive in the market. Fingers crossed for you, I wish you luck!
