There is no way to comput the play time of an unseekable file. If you 
can't seek to the end you don't know how long it is. This is by design 
as part of the bitstream (as opposed to file) orientation of Ogg.

So, buffer the file until it's done? If it's a static file on the other 
end, you can estimate from the size (e.g. from http headers) and average 
bitrate, or otherwise pass it as metadata.
