Hey Jakob, my goal is to actually get rid of the dependencies... if we go through all the trouble of porting them to D6 and debugging them, we may as well remove them altogether and accommodate the changes in the source. I suppose that's technically creating new features, but I think it's better in the long run. I've already devised a replacement for TAPIr, and I'm pretty sure we can just remove uBrowser from core with almost no headache. This has mostly been in the spare moments I get between projects w/ Lyle here in the office, but soon we should start coordinating through http://support.ubercart.org/project/32.
