There is no "formal" definition. FAST_SEEK is a "cheap" seek with little 
or no delay, typically a local file system, typically NOT a network 
protocol that requires restarting the protocol state machine, and 
waiting for multiple round-trips.

Implement slow SEEK in FTP if not already done, and either fix libavi 
not to seek, or to use slow seek, or if it would really need to much 
seeks, keep it the way it is, and instruct people to download the file.

I would not use AVI for progressive download...
