This is great, and I'm genuinely excited by the prospect of a modern set of tools to replace some of these existing systems which, while rock solid for decades, are beginning to show their age.

I think once things are a bit more settled, I'll be interested in the client end of things... That's something that I didn't see much on the Stalwart website. Yes, I'm sure I could run the same set of tools now, but that seems like a waste of an opportunity.
