That's right, I have plans to route lightvc seamlessy with drupal.
This will be possible by checking the request into drupals core api and if there is no result lightvc will then route by it's static routes to controllers. By using a similar pattern you can intertwine vastly different applications.
Another possibility is to have lightvc configured to use drupal phptemplates for lightvc controllers. This would make drupal a useful tool.
I might also mix in a quick crud per table into my apps. Every run of the coughphp scrape, all new dbs and tables will be able to be accessible by clean urls. Then per db or table you could set the layout variable for lightvc. For DB somecompany,set layout somecompanyv2site. This will make admin interfaces easy, especially with authentication available by drupal.
