Internet and movie on Amiga 500?

[Borut]

I have two very curious questions to ask. Is it seriously impossible, literally, impossible for an Amiga 500 to have high speed internet connection even if the person upgrade the CPU from 7 Mhz to 50 Mhz? Can the person still have high speed internet connection like that of the Amiga 1200 and 4000 series?

Also, if a person have 50 Mhz CPU is it also impossible to be able to watch movies on the Amiga 500? Is it really far fetched to watch movies on Amiga 500? Because a simple mp3 player I have, it is tiny screen and it is not even a computer, or anything, it is a very inferior hardware spec for mp3, allows you to view images and play movies with sound by converting the movie from avi to mv or some format? So why can't Amiga 500 with 50 Mhz be able to play movies when Commodore 64 can play movies on 20 Mhz CPU running WINGS computer?

Not a big problem for movies: http://www.youtube.com/watch?v=pgdJAj3jty0&feature=youtube_gdata_player
