[Tramline-dev] Re: a Plone file-Field with tramline and JUpload ?

[Matt Hamilton]

Dirk,
   Good timing :)  I am currently at the Snow Sprint in Austria with 
Nate working on improving the Tramline support.  I agree with you that 
the best approach will be to set a specific header to only invoke 
tramline for specific content types.  Tramline itself does not currently 
support this, but I am looking to add it in -- either in tramline or 
perhaps as a conditional directive in the apache config.

Other items we are working on here:

* Getting ATAudio and other media types to be tramline aware
* Conditional invoking of the tramline filter for specific media types
* Using sha-1 hash for tramline filenames so as to be compatible
   with Limewire 'magnet links'.  This could allow content from Plone to
   be served directly out onto the gnutella network
