I'm not aware of a CPAN Module, but that's just me, and yes, I think it could be CPAN worthy. You might want to post the POD as a RFC meditation to get more feedback.

But without looking at the source, I see two distinct tasks in your hack:

• convert a nested HTML list into an internal tree (probably via some HTML parser)
• output that tree as JavaScript code

There are some modules which do the first part, not necessary with HTML input. Pod::Simple::SimpleTree comes to mind. I would suggest to provide the JavaScript generating via your module with interfaces to existing tree generating modules.

On the name - maybe Tree::JS::dTree, since it could be used for other trees than just HTML lists?

Minor nit - your converted page lacks the TOP id in the box div :-)
