My guess is you're confusing XBMC scraper (which scrapes a website/API for metadata information about movies or tvshows) for an XBMC python add-on which may scrape a website (but doesn't have to) and returns playable URLs.
Moving to the add-on dev forum.
Yes, both are what in XBMC-land is known as python add-ons.
bigtuna, you should get in touch with Eldorado or come visit us at xbmchub.com. There are two libs in development that could benefit from your experience.
Urlresolver takes host urls, and resolves them to playable file urls.
Metahandlers allows addon authors to gather and display meta data for list items (the XBMC scrapers can't be used by addons)
I'll checkout xbmchub.com.
