OK I guess its learning curve time again.
As far as email, backups, sharepoint and remote web go, I'll put those on the backburner for a while. One small question I have about remote web though is, whilst you say it is like remote desktop, is this remote desktop without having to tie up a computer in the office? If so that is very interesting and potentially useful.
Unfortunately, no. You connect to the server using RWW, and from there connect to your desktop. It uses the RDP protocol, but you don't connect directly to your desktop; you authenticate to the server first. This gives you full access to the server resources, so that when you get your PC, it looks as it would in the office.
