Read the HTTP specs. You can upload (PUT) files with HTTP.

Because it's stupid to route all the traffic through the server.
- Your files are binary data, XML is not very good in handling that,
- you generate much unnecessary load for the server.
I don't think that file sharing over jabber is scaleable. I will maybe
work with a few clients but not a the scale of a grown up P2P network.

Both protocols have support for passwords that can be used for that. If
passwords a not good enough you can use http over SSL with certificates.
Also you can make checks based on the accessing IP.
By putting the data over a raw TCP/IP connection there is now additional
security (I even don't think there is ANY security).
But using HTTP as transfer protocol has the one big advantage that it
will even work over proxies.

If they don't wont to offer you can't force them to do. If you try to
they will even not use your product.
Use as much existing protocols as you can and the support for your
protocol will be much better. It has to be easy for developers to add
support to their clients. They don't want to implement everything from
scratch.
And to me your protocol does not only seem to be the reinvention of the
wheel ... it also seems to be much to complicated. The simple protocols
rule the world. Look at the protocols that are in wide use at the
internet: TCP/IP, SMTP, NNTP, IRC, HTTP, ... they are all damn simple.
