I would not worry about that for two reasons:

1) Like I said, XP only supports one user, whether it be local or remote at 
any given time. If someone is using the computer locally when a remote user 
tries to connect, they will be asked to relinquish control of the computer. 
I never really tried accessing XP as a second remote user while the first 
was already connected but I would assume that you will either be prompted 
to relinquish control as with the local user or you will be told that you 
can not connect.

2) Unlike VNC which uses port number (5900 + the display number), the port 
allocation for ICA and RDP is dynamic. With most servers, the "well known" 
port number is typically only used for the initial negotiation of an 
alternate dynamic port, much in the same way as http web servers, which 
work on port 80, can accommodate hundreds if not thousands of connections 
at the same time.

These "dynamic" port range is usually between 49152 and 65535 and is not 
blocked by the firewall. This isn't usually a security problem since there 
should not be any services running in that range of ports. The only time 
there is a service showing up in that range is when it has been 
pre-arranged by a server and client. I am sure there must be some kind of 
negotiation that goes on with most protocols to ensure that the connection 
is actually being made by the client who originally requested the 
connection and not someone else who got lucky. DISCLAMER: Note that I 
haven't actually read any RFC's on this. I am just assuming that this is 
the way it works based on my observations and experiences.

As for dns2go, it won't help you here because dns2go won't give your 
network more IP addresses than you have. It's like the address on the front 
of your home. You can get lots of post office box numbers as aliases for 
your home address but you will still only have one number on the front of 
your home.
