It's severely looking like it'll be a nasty hack to make this happen.  
We pride ourselves on dirt cheap setups that do what's needed and are  
rock solid - and it's looking like high availability on the windows  
side of things is gonna involve expensive hardware for microsoft  
clustering, or expensive software to do the highavailabilty automation  
without ms clustering.

So I'm seeing two Linux boxes with a windows server virtual machine  
and NLB configured on each - along with SQL express or ancient ms SQL  
installed. Those just act as a connection front end and pass queries  
on to a Linux based HA backend. Or possibly a windows OSS backend that  
has it's own HA stuff (skipping the VM stuff).

Mysql's clustering backend has lots of Linux love, but is listed for  
development only under windows. Postgres's SLony stuff looks to handle  
replication fine under windows, but doesn't supply automagical  
failover/heartbeat stuff. Either backend plus heartbeat under linux  
offers what's wanted, and brute forcing the matter with DRBD under  
Linux is possible as well.

So, developer status mysql cluster engine under windows, or virtual  
machine windows to a linux postgres/mysql back end. I have much more  
postgres experience.... Sooo.... Leaning that way.

I'm open to suggestions, but keep in mind my resources for the project  
will make most any admin cringe :)

Linux for the win!
