Splasm Software Discussions

I have been looking for an application lately to keep an inventory of my DVDs. I have found quite a few, but they have been either lacking in their features, or have been way too bloated with too many features. What I'm looking for in such an application is:

-A Mac desktop application for entering / editing information
-An iPhone application that would automatically synchronize with the desktop version
-Ability to edit entries from the iPhone
-Store data such as:
--Basic movie details
--Loan information for borrowing movies out
--Ability to handle multiple discs, TV shows and box sets

I know this project would be a major undertaking, but with the quality of Splasm's previous applications, I know something like this would turn out great and not suffer from some of the issues that other issues I have noticed in other applicaitons.
