There is no foolproof way to avoid that. If one does not specify an upper
limit, programmers will /assume/ one and the situation will be worse
because they all will assume something different.

The only thing one can do is specify a ridiculously high limit and pray
that it will not be exceeded during the lifetime of the product.

No. Speed should be measured at the physical level after any compression.
Rates measured on the uncompressed side are meaningless since compression
rates depends on the type of data.

Calling it 400 kb is sales talk.

Don't get me wrong. I am /not/ advocating an upper linit of 128 kb. The
limit should be much higher. I a thinking in the order of 1Gb/s or so.

Exactly my point of view, but it is too late. The djin is out of the
bottle. All we can do now is damage control.

Cheers, Michiel
