First off I like your theme, but since I am a lowly programmer, my opinion isn't of much use to anyone.
In looking at your README file (which isn't identified as text/plain) it seems that you require users to modify essentially every instance of ad_form and list builder, and change a few tcl and adp files.
This is not the definition of a module (or package), as modules have to accept core conventions. But more importantly, could you suggest potential changes to core which would allow easier 'themeing'? I'm asking because it is not clear if your modifications are necessary because of a deficiency in OpenACS or in your module. You should figure it out and explain it, because you really should not offer modules which require changes to core. IMHO, you should not create them in the first place, but what you do on your own site is nobody's business.
