An idea that springs to mind is that you could run a VPN server at home which 
the remote computer connects in to. It will then have a 'normal' IP address 
on your local network. Then when the machine is at home, you can setup a 
static lease in the DHCP server to allocate the same address the machine 
normally has over the VPN (or if your router doesn't give you this option, 
you could always set it as a static IP on the machine itself).

Therefore the machine always has the same IP address when at Uni and when at 
home just as if it was on the home network all the time.

I am in a very similar situation, but my Uni doesn't allow outgoing VPN 
connections for some strange reason... :-(

HTH,
David.
