Depends how integrated you want it to be. Could be as easy as
defining a new DOWNLOADER [your app] in lynx.cfg
What really interests me is; who feels like teaching it to parse
JavaScript as well [if you're releasing the source and leaving
it open to changes]?
People seem to think adding support for JavaScript isn't practical,
and maybe impossibe, in Lynx because of its a one-pass HTML parsing.
A separate application that *could* make sense of JavaScript,
then pass the results to Lynx, popped into my head some time ago
but I don't know how to do it.
Here's an old message about it:

The follow-ups are probably more interesting than my input.
