i'm not sure how useful it would be to people to open source F+R since it is written with borland c++ builder, a commercial compiler (doesn't mean that it can't be open sourced, just that it's not nearly as attractive to open source community as a program that can be compiled with free toils).
my other concern of course is with regard to donations. there are a couple of apps here of mine that are open source, including a very popular irc encryption addon, which really doesn't get donations. i'm not sure if people would be less inclined to donate to the site of F+R was open source, and if other versions were written an distributed by others.. maybe we can think about a new kind of open source license that says it's open source but derived versions should somehow redirect people to still visit this site? i'm not sute..
