Title: high-availability on MS Windows cluster -- need insights

I'm looking for someone to help me understand the tradeoffs/alternatives/problems for high-availability on MS Windows clusters.  Willing to do it on this emaillist, but if that is too much traffic, can go direct email or phone. 

I'm not actually the end-user/DBA for the task.   I'm (among other tasks) the Boeing OSS Toolkit product manager.   Postgresql is one of the (currently) 500 packages.  I provide support for selection, build/install/configure/use on a variety of UNIX and Linux systems, from laptops to mainframes, plus (usually binary) installs on various MS Windows systems.   

A user asked for help re high-availability on MS Windows.   While I'm semi-competent with postgresql on single machines, I'm no cluster guru and only do MS Windows under duress.  After some searching and reading, I asked for help on comp.databases.postgresql, where I was redirected to this maillist.
