all I'm suggesting is a 6.x-1.0 version of ubercart, nothing more. From what I'm hearing though is that I'll have to fork my own version of ubercart to work with 1.0 dependencies until the Ryan and Lyle come up with their own D6 version, which should probably be named 6.x-2.0-alpha1. When this 'official' release comes out, my version will no longer be needed.
Also, my version would be fully compatible with all contrib modules that are version 1.0 compatible, given that they can be converted to D6 as well.
Since 95%+ of the code will be the same, I'm guessing/hoping that my code will be a good basis in which the uberteam can make a good D6 release -- this should gain them about 2-3 weeks of dev time in grunt converting of code.
That all said, if anyone has dev experience, and especially D6 dev experience or wants to learn, I'd love some help. The grunt conversion process is done (using coder.module) but there are a lot of API changes that need to be looked at, especially regarding the new forms API. Send me a PM if you're interested.
