Splitting asUnder

I am considering splitting UnderTheHood into about 10 smaller applications.
Initial thoughts can be found Here.
Your comments are invited.
My motivation comes from two major sources:
(1) Lily Chambers has shown me the wisdom of offering a smaller application as a pay-per-download item.
(2) I am finding a 2MB template a heavy burden in terms of maintenance and documentation.
By spending some splitting Under asunder I believe that I will gain time and money in the long run.
