I second Tomtuttle's suggestion and would think seriously about taking down the fan...replace it with a low-profile light fixture, then before moving replace the fan. Not hard to do (in case you haven't done it)...just kind of awkward. Make sure you've got a sturdy ladder, etc.

Good luck! I'm envious BTW...have a 32" regular TV but would LOVE to get something bigger...want to see what happens in the DLP field this fall...
