So you're running 64-bit Ubuntu with 32-Bit Firefox on the server and
presumably a 32-bit thin client system.  I've personally never run flash on
64-bit ubuntu.

To be honest, for a multi-user desktop system, I'd recommend you use 32-bit
Ubuntu, not 64-bit.  The 64-bit is fine in my experience, except when it
comes to proprietary stuff like flash and java.  The 32-bit should install
fine and you can just run 32-bit versions of all the apps, rather than
having to use nswrapper.  It's not exactly clear to me why libflashplugin
doesn't work, but I'd guess it may be to do with it being a 32-bit library
trying to access the sound card via 64-bit alsa infrastructure.

Are you running Gutsy?
