Another thing we are wondering about is the improvements you guys are proposing on top of TE. Some of these things could be very useful to existing customers. THAT I can see paying for, but we are Source already so maybe things get a little tricky there. Would be interested in what options, if any, there may be there for existing source customers to buy into the new improvements coming from your end. Of course there could be a bit of a mess with trying to make sure versions match up as well - both Dyox and Junglee having a synced REPO or Git or something similar could really be in improvement on the update/distribution process. Source users already have Construction Kit. However, with the new proposed voxel building tools that may be coming, that could be a paid for add on for all TE owners. If the older customer base doesn't want to pay for the new tools then we still have construction kit to fall back on.
