This is not possible and it is very likely that it will never be implemented in ZotPad because Zotero will soon provide an official solution for this: Zotero bookmarklet. The bookmarklet was announced during summer 2012, and is currently being tested by users. Because the bookmarklet is not yet thoroughly tested, bugs may still exist.
The bookmarklet works similarly to Zotero connectors. You can save it on the bookmark menu on your iPad or iPhone. Opening the bookmarklet will send the current webpage to Zotero server, which will use Zotero translators and save the page as a new item in your My Library.
