EDC Topic suggestions?

The next
Embedded Developers Conference is May 10-12 in Vegas.  I haven’t submitted any
proposals yet, but plan to submit presentations on developing TUX based tests
(mostly the same as I’ve presented before with some additions / improvements),
and possibly a presentation on writing diagnostic tools for embedded devices.

Are
there other test or diagnostic related topics of interest to embedded
developers trying to get quality devices to market?
