Hi,
thanks for taking the time to write such an elaborate reply! I guess, being able to take your working machine with you (it being a laptop) must be the most comfortable solution. I hope to have this setup as soon as possible, but this will have to wait a little due to financial reasons.
Copying/Mirroring the code bank to the other computer sounds like a good idea, maybe this will be my next step.
I know about Version Control Systems and this might be the most professional way to do this. Until now, the technical stuff involved with that always scared me away. I thought that i had to install the svn repository on local machines which wouldn't have helped me much in my situation because i still would have had to keep two systems up to date. But i will definitely check out your suggestion with google code, which i wasn't aware of.
thanks again!
Sebastian
