Tor - Black Belt Edition for Windows - Tor Client + Tor Server(with accounting) - sideBYside

[Cav]

Hi Roger,

Thanks for getting back to me so quickly. I have read your email and 
admit to being a little naive. For one I did not realise Tor is pushing 
/ pulling 600mb per second !
I note your raised points about branding, and that I could be implying 
its an official version, which I should not be doing in any case.

The reason for the 2 stacks is to enable hibernation of one without 
affecting client behaviour, as you identified. It will be great when we 
can both hibernate and still maintain client connectivity.

Based on your comments and those of Robert Ransom, I think its best to 
cease work on this version and not distribute it. As you mentioned 2 
stacks will result in double the descriptor traffic - which is not a 
good idea. I was aiming this at home users who may have a small amount 
of bandwidth to spare, but as you again mentioned, it appears this may 
not help all that much, given the volumes in the network now.

Thanks for the comments and input. I am relieved I sought some feedback 
before taking things any further.

With kind regards,
Cav Edwards
