Discussed with Kiwidude and releasing both plugin updates here for now.

Modify ePub 0.3.5 Beta - 26 Jun 2011
Fix an issue with css margin rewriting that created property names using '_' instead of '-'


Quality Check 1.5.9 Beta - 26 Jun 2011
Add the ability to compare ePub css 'book level' margins to Calibre Preferences
Add a check for ePubs with no 'book level' margins defined
Add a check for ePubs using inline @page margin definitions


Modify ePub still only operates on CSS files, but I'll be working on an update to modify all CSS including in-line in the near future. I wanted to get this release out to fix an outstanding bug - if you've rewritten any ePub files' margins using the previous plugin you'll need to do it again with this version.

Quality Check will check all types of css margins on body or @page, including Calibre generated in-line ones.

EDIT:
These have now been officially release and can be found on their respective threads in the Plugins forum.
