Certainly... we've only had it "in production" for a couple of days now, but based on yesterday and today (and our old intranet statistics), we get approximately 21k hits per day; "Unique" visitor, not really certain how to find that info but we have about 800 employees that hit this every day and multiple times throughout the day.
The hardware equivalent for our VM machine is: Dual-Core AMD Opteron 2.6ghz (Processor 2218, dunno what that means); 2gb RAM; 20gb HD (easily expandable), Windows Server 2003 SP2; anything else relevant?
As for our #2 solution, I have a copy of it available (free, no registration required) on my personal website. It is a really simple module and could use a little work but feel free to download it. The only requirements to run it are turn OFF anonymous authentication on the virtual directory, turn ON Integrated Windows Authentication, and then drop the module on whatever page (typically the home page) you want to trigger the autologon.
I'm working on an auto-logon module that will have that feature as well as several other features in it and hope to have that completed in the next couple of weeks. It'll allow login-switching (I know that already exists out there), as well as "querystring" logins, and then some other features.
