Let me cast this is a more favorable light. Suppose you have
user validation running (through the server, or throught th form).
You may well want to have per-user limits on dik storage; or, you may
simply be short of disk space. It would be nice to inform the user of
these facts *before* the start of a 200 Mbytes transfer --
particularly when someone is paying per byte or packet transfered.
Rough prediction of available space is not hard. Frequently,
rough predictions are all you need for a production system.
