might be just (my) wild guess: but distros that don't support dual-arch 
32_and_64bit simultaneously will have a hard time to get both wine 
implementations of both win32 and win64 to co-exist that easily. iow. 
none drinks from wine that's spilled over the table ;)

otoh. distros that do separate /usr/lib64 from /usr/lib (ie. where the 
former shall not be a symlink to the later) might have an edge here: 
fedora and opensuse might be examples where win32 VSTs might work over 
dssi-vst and on x86_64 systems without system disruptive kludges.

that said, my old dssi-vst builds on opensuse13.2 [1] have been capable 
to run win32 VSTs under qtractor.x86_64 at least.
