Hm. I admire your courage, and hope you do this for educational purposes only. You maybe want to register your effort with the Perl Power Tools project, they don't have the vi command in stock yet.

As a feedback on your program, on my machine (linux) it produces a lot of garbage like this (running inside an ssh terminal): 

> perl vip.pl
--> v_screen::new
--> v_screen::init
                  --> v_window::new
                                   --> v_window::init
                                                     --> v_file::new
--> v_screen::execute
~                    --> v_window::command
~                                         --> v_file::command
~                                                            --> v_win
+dow::draw
~                                                                     
+         -
-> v_window::position
~                    --> v_file::position
~                                        --> v_file::topline
~                                                           --> v_wind

Maybe you can give more detailed instructions on how to build, run, test it, etc, for those interested.
