Great, thanks.  And yeah, IE support is dicey at best.  I think the
ideal is that we at least downgrade functionality gracefully, instead of
failing.

I have been playing with your patches, and they seem to work nicely.
I'll try to comment more formally on the v3 set.

My remaining comments have less to do with your patches, than with the
whole process.

I have to confess I'm pretty ignorant of the whole file transfer
function.  There are some ways it behaves that seem less than ideal.
There is no progress bar, I take it?  And do we really transmit in that
small a chunk size?  And we preallocate the whole file before filling in
the bytes?

I worry that the net result is going to be (and is currently)
potentially confusing.  I drop a 4G file on my browser. Nothing happens.
 I drop it again.  Now I've started a many hour process that's going to
run in the background.

Also, on the file preallocation, I worry that I'll go look, think the
file is complete (because the size is right), and then copy off a
corrupt version...

Do I understand correctly, or have I just horribly mis-configured my agent?

Cheers,

Jeremy
