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

[Nate Aune]

Hi Matt,

Could you provide a summary of the improvements that were made to  
Tramline/PloneTramline during the snow sprint? We need this summary  
for the Snow Sprint wrapup page: http://plone.org/events/sprints/snow- 
sprint3

Any chance that you can make a 0.2 release that incorporates the new  
features?

Also, there was product just announced on zope.org called  
ThreadedTransferAgent which is described as a "Upload and Download  
Monitor" showing how to monitor uploads into Zope. http:// 
www.zope.org/Members/TheJester/ThreadedTransferAgent

 From the README.txt:

=======

This is a demo of how to build an upload monitor for Zope. It consists
of a CGI and a Zope Product that does the monitoring. There is demo code
to show how to utilise it in your products. It's functional, but, not
necessarily meant to be a turnkey solution.

There's also code present (but disabled), to demonstrate how to
process large files and provide a status inside Zope (and then a
download if you want). It needs customisation (a worker thread e.g.),
to actually work.

=======

I haven't looked at the code yet, so i don't know how robust is is.  
And the fact that it's released as version 0.0.0, is a bit  
disconcerting. Isn't 0.0.0 reserved for vaporware? ;)

Anyways, might be something worth checking out.

Nate
