> With a bit of tuning you can make it start a terminal emulator window inside Vim, and have it send the current paragraph of your source code into it with a press of a button.

Defining keybindings for splitting the window, opening a terminal buffer and copying a paragraph does not really require a plugin. That's one of the features I like most in Vim, its ability to just map any input to another sequence of keypresses can replace whole scripts and plugins provided you're fine with readability comparable to regular expressions.
