I first came across UltraEdit as a tool to edit UNIX files on Windows, instead of messing around with telnet and vi: It was a fine text editor with an integrated ftp client that let you easily open, edit and save files to a Unix machine from the comfort of your desktop.
BVRDE is much more ambitious than that: it tries to be a “Remote IDE” for editing, compiling and debugging Unix projects from a Windows machine, transfering files with ftp and talking to make and gdb through telnet behind the scenes. Like a lot of cool editing environments recently, it uses Scintilla.
