The above should work quite well but just remember that you need to employ the same security on his [b]Home [/b] computer as you do on your network or you could have a massive infection spreading out of control across the Domain in no time at all.
When I do this for Companies that I support I make them supply a NB for the user to take home and log in so that they can access the network but I still have control over the security.
Most Home computers are used by the kids to play games surf the net and are horrendously infected with both Virus and Male Ware/ Spy ware so you need to prevent this from happening.
On the good side according to MS using Remote Desktop should only be something like 4 mouse clicks away, while it makes life easier for the CEO it makes the life of the SYS Admin a nightmare as they are blamed when the CEO logs on and compromises the system from their home computer.
