Curse of the bleeding edge - SQL 2005 Express and CRM 3.0 'fat' client

Is it possible to use SQL 2005 Express with the CRM 3.0 'fat' client instead of MSDE? I'm tempted to try it but I'm also worried that it might break my install. I haven't seen much mention of it but I've been such a fan of SQL 2005 over SQL 2000 that I'd really love to give it a shot.

I can't seem to find much on the internet about people trying it.

Please drop me a line if you figure it out.

It looks like you can run the server portion of it on SQL 2005 according to this link:

No mention of the client.
