I'm picking in the dark but if you use Win7/Vista on both computers and dropbox can be issued a drive letter, maybe as network drive you can use symbolic links to redirect paths. It's a little commandline tool that comes with Win7 called Mklink that can do it.
When I installed a raid system I was too lazy to reinstall my games and other apps on the new location. Instead I copied my files to the new drive and used a directory junction to redirect the path. The games and for this matter the OS still think they are on E:\Games when in fact they are relocated to F:\Games [:)]
Here some info about Mklink it usage and what symbolic links and directory junctions are and how they work.

There is also a little app with a gui interface if that is easier for you, if the HDD's are formatted with NTFS it works on WinXP too.

Always backup your data first!
I will give you an example but remember, first I DON NOT KNOW DROP BOX, it may be not possible to do this way. Second I never used MKlink on network paths. There may be unforeseen consequences! Third read the links I gave about MKlink completely. Understand what "Symbolic Links and "Directory Junctions" are.
I assume for this example you can give drop box a drive letter.
You give drop box on both system the letter Z:\
Default path for your saves are "C:\Users\[User Name]\Documents\My Games\Panzer Corps\"
First copy the complete Panzer Corps folder from "C:\Users\[User Name]\Documents\My Games\Panzer Corps\" folder to Z:\
Now delete your old folder. "C:\Users\[User Name]\Documents\My Games\Panzer Corps\"
Then link the new location with the old using MKlink
MKlinK /J "C:\Users\[User Name]\Documents\My Games\Panzer Corps\" "Z:\Panzer Corps\"
The Panzer Corps folder you just deleted at C:\ should reappear but with a the link arrow on it and when opened with all the files you copied earlier.
Repeat this on both computers. Now when panzer corps create a save or load save it will acces the old location but be redirected to Z:\Panzer Corps\ instead.
