Oh I believe you can ‘stream’ stuff at 2 fps over a 500 kbps line alright, the ‘not serious’ part is how anyone could find that acceptable. Even if all you have is 500 kbps...

If you would use your 2fps streaming browser to read, say, hacker news, every scroll operation would be hideously slow and pull in another ~60KB per second, even though the page data itself is only a few KB and never changes. Your ‘streaming solution’ only makes sense if the total amount of data to fetch for the page itself outweighs the total amount of data for all the frames you need to stream while you are using the page. Which is probably almost never, unless you always look at static single-page applications which continuously pull in data on the backend without presenting anything new at the front end. Highly unlikely.
