This page hosts a virtual floppy drive emulator (?) for Windows. It seems to work OK. It loads several different image formats. Read and write support.
I originally was looking into this as a way to create Windows XP ASR backups without a floppy drive - however, it turns out a floppy isn't necessary anyway... but that's another Scribble altogether.

Virtual DVD burner. Going to try to use this with HP Recovery Media creator to get an ISO, instead of a handful of DVDs (been there, done that...)
