at least small seeks forward are handled by just discarding some data
and so have no performance impact.
All types of seeking should generally be supported with http/ftp, but
it's really slow.
When using pipes you really can't seek backwards except if you implement
a cache that keeps some of the already read data.

If they aren't in that order it's a non-interleaved file, those never
work properly over network/pipe anyway.
