I figure that Atlantis will be freely downloadable and will use all the features for the first 30 days after install, or so. After 30 days, it will disable the MUSH Text Editor and a few other things (Perl scripting? Plugins?); if you don't need those, then it's just free. If you want those back, it'd be a $10 registration fee.
Basically, I've done a ton of freeware / open source stuff in the past, and never really gotten anything from it. I figure, this time I'll try and earn a little back. $10 doesn't seem that bad to me; it's less than Savitar charges, and will last an entire 1.x.x line. And to renew a license for a full version change (like 1.x.x to 2.x.x) will be like $4 or something. And since I don't foresee doing 1.x.x -> 2.x.x jumps very often, as opposed to 1.1.x, 1.2.x, 1.3.x, etc., I don't figure it's a huge cost.
However, I'm also committing to the fact that there will always be a free version of Atlantis as well, and if years from now I ever reach the point where I absolutely have no more time to maintain Atlantis, I'll release the source rather than let it become another forgotten / dead-in-the-water client.
Hopefully that helps clarify.
