some questions about uploader

[Anastasia Cheetham]

Justin, these are some excellent questions! Thanks so much for doing  
such a thorough job of testing.

I have some technical questions for Eli:

I assume this would mean actually deleting any already-uploaded files  
from the server (e.g. if I pause the upload after 2 of 5 files have  
been uploaded, then cancel, those 2 uploaded files would be removed  
from the server).

Does the underlying SWFUploader (which carries out the actual  
communication with the back-end) allow this action? I might be  
surprised if it does, as this seems like quite a security risk!

What does the underlying SWFUploader object do with files of the same  
name? Does it just ship them off to the server and rely on the server  
to let it know if the server can't/doesn't want to handle the situation?
