There are several blogs that have discussed how to share an auth cookie between sites in a farm and how to do a true single-signon for a domain. Mark Brooks pointed me to these that help a lot:

As many of you might not know, I am not at the PDC, but am interestingly watching to see what comes out from it.  Usually at the event times, everyone blogs too much about what they like and don't like.  Everyone wants to be the first out the door with some news from a keynote.  So I am layng low and letting all that happen without me.  On the plus side, I can now talk about some things that I've had the opportunity to play with for some time (now that they are public knowledge and I am not hurting any NDA's):

I installed the new version of iTunes recently and its amazing how many running services and background tasks Apple is installing:

I've spent a couple hours digging back into the new WinFS.  So far it seems interesting, but only as a new datastore.  It doesn't seem to be trying to be the Object File System from teh Cairo days, though that may be because of it's bolted-on status on XP.  It is still stored in a SQL Server engine, so that is good.  It also looks like the actual files (not just the metadata) are being stored there. 

Trish and I decided to move into an old stomping grounds of mine inside Atlanta proper.  I always forget the nasty little things that can make a move feel like hell.  In this case, the AC in the new apartment was(is) broken.  I thought we could tough it out, but once the cats started to pant...I had to do something.
