yeah.

and, in fact 10Hz asynchronous throughput is possible... (this is 
typically how most online gaming works).

one can't reasonably get 10Hz synchronous (IOW: request/response), due 
to ping times, but this is a different matter.

I am not claiming one can do request/response at 10Hz, as this probably 
would be impossible over a WAN (at reasonable ping times).

online gaming generally isn't based on request/response though, so the 
problems of not being able to get responses at this rate don't really 
matter too much (the user may still notice the results of bad ping 
times, namely stuff being out of place or seemingly teleporting around 
or similar, but this is a different issue).

TCP has a throughput limit due to ping, where assuming unlimited 
bandwidth but a 200ms ping, one will still be limited to somewhere 
around 320kB/s or so (assuming a 64kB window).

however, as is, there are typically bandwidth constraints as well (but, 
they are a little more subject to fudging).

the main goal is mostly to send everything at a bandwidth low enough 
that the connection doesn't risk getting backlogged (depends on internet 
connection, but 16-32 kB/s seems reasonably safe, as internet radio 
often tends to operate in this range, say, 192kbps is 24kB/s).

stalls are also a potential risk as well.

or such...
