Depending on your requirements, you should either be doing what spiv suggested
earlier (e.g. "nothing, just call transport.write") or you should be looking
into the producer/consumer API, which will allow you to produce streams of data
on demand.  Last I checked this wasn't terribly well documented, but it's
fairly straightforward and the code in twisted.web.static.FileTransfer is a
decent example.
