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.
