Yes!  A fine decision.
Couldn't help but notice there isn't a DOS supported.
When I get a hold of your libwww 3.0 I'll be adding this; BTW, when can I 
	lay my paws on it?
I'll be wanting to coordinate any changes that I make with the CERN group.

Let's discuss this POST and PUT information, just for clarity if nothing
else.  When doing either in HTTP, you'll be able to specify multiple
destinations for the data.  If post transactions require a URI returned,
how is this handled by the libwww when multiples come back? Or am I off
base here?  Note, I understand that the URI is no guarantee of any action
taken by the server.  Does the put return a URI also, or just
acknowledgement of a change to the URI sent by the client? 

The nntp post is handled all in one transaction, so only one message ID 
is given back from an nntp post; even if multiple newsgroups were 
targeted because nntp can handle this all in one request.  Good.

The sentto URI is a decent idea, but why not depend upon SMTP to return 
to the user a message that never reached it's destination?  Also, 
shouldn't this be similar to the nntp idea, since you can specify 
multiple recipients of the message BODY while doing the transaction with 
SMTP.  If so, how does the sentto URI cover multiple SMTP targets?

I think the FTP POST is a needed feature in your design.  I know that it 
is going to be very open so that it can be added in the future.  I just 
wanted to give my vote now.

Good luck, Henrick!
