I've uploaded a new release of fTelnet...nothing too major in this release (aside from open sourcing under the GPLv3), I've just disabled the min/max buttons (confusing to users), and added Amiga font support (as per a user request).
I've also implemented a few more features to HtmlTerm (such as file uploads), but I've also transitioned from a proof-of-concept to a full port based on the fTelnet source, and the port isn't ready yet so don't look for the new features to be available on the test page yet. Soon though!
