I installed the most recent bidwatch 1.3.6 from the source tarball. I can start it, sync the time, but it didnt download the bids.
I searched the sourcecode and tried to change all .com URLs to .de (I am from germany). But it didn´t work :( I guess the webdesign is different, so bidwatcher wont work for eBay Germany.
You use the eBay US time to synch the clock, so it wont be possible for non-US users to use bidwatch :(
