Your order is pretty good, Jack;  based on what's been getting the support,
I'd say AIX, Win2K, Solaris -- alot of focus is being placed on Win2K, ref.
the LTO sales activity, MSCS support, etc...  and, for sure, don't add
platform learning curve to new product.  Also, multiple TSM servers can
coexist on any platform, but they pretty much require the same level (ie,
only once instance of the installed binaries),,, see the QuickStart book for
the platform choice to see "clues" about doing it (it's somewhat intuitive,
provided you know the given platform).
