It was a great session hosted by LBi and many thanks to @TheRealRiaz for hosting and Matt Taylor (SUGUK) for organising.
The session went really well (my VMs were a little slow to warm up) but thankfully the demo gods smiled on my and my demos actually worked! (huzzah!)
We managed to go from a full NTLM SharePoint 2010 farm to configuring Excel Services to use Kerberos Constrained Delegation to SQL Analysis Services, and configuring the Web Applications to delegate to each other (to sort out that pesky RSS Viewer Web Part) and all in about 45 minutes!
For those who missed it, or wanted some notes from the session, you can access all of my slides below:
