Is there any way I can incorporate Core Data into the app so that I can do away with using MySql? i.e. log into the app on one machine (using it's SQLite database) from the same app on a different machine?
There are two problems with this —First, sqlite isn't a db server like MySQL. It's an in-process library that directly manipulates the database file. It's possible to write a server around sqlite, that will respond to SQL queries over a socket (and I think it's been done) but the API to use such a server wouldn't look like the sqlite API, so you wouldn't be able to get CoreData to use it.
Second, CoreData really isn't meant for having two clients (whether users or processes) accessing the database at once. I think it's possible to do this, but it requires extra work to get each client to detect when the other has changed the db, and invalidate its caches.
