Vista - Suggestions

Is there going to be a commercial version that will be able to support Larger
files??
Also, is it possible to integrate a P2P schema for this?
We currently have machines that are on clients as our presence devices. We
use this for our SOE images as well as deployment servers etc. We plan on
using FolderShare to syncronise between all of our clients, however the 2GB
limit does not help, and I have noticed that each file comes from a single
machine only. We were planning on having our system use some kind of Peer to
Peer system to ensure uptime as well as increase the transfer speeds.

Would it be possible to on the web site 'rename' the computer's?
We currently (and will be for the forseeable future) be having computers
with the EXACT same name sharing between each other.
Currently this is coming up in the format of
<NAME>
<NAME>1
<NAME>2
<NAME>3

It would be most advantageous if we could do something like
<NAME>-SydneyITDepartment (or something else.....)

Also would it be possible to change the ports for incoming initated
connections?? Sometimes its a bit hard to get ports 80 and 443 open on all
of our internet links due to already hosting web sites....
