I recently found the IUP library for lua and used it to make a simple program shell, and a very basic text editor. In addition to running FBlua specific scripts, the shell and the editor can also run Lua Player scripts by making a call to the windows version of lua player, but you will need to put the luaplayer.exe into the luaplayerwindows subfolder (note: the results you get from the windows lua player might not be exactly the same as what you get from the psp version)
I do intend to add more to the editor like function highlighting and stuff, but that will have to wait until tecgraf releases the scintilla module for IUP
P.S. the included readme file hasn't been updated, and truthfully I don't even remember what I changed in FBlua since the last release
