WPE 9 on Snow Leopard

[PBainbridge]

Would anyone know if it's possible to run the FMSA9 Web Publishing Engine on a Snow Leopard Server? We have a two machine configuration, both OS X 10.5 Server, with FMSA9 on one and the WPE on the web server. I'd like to upgrade to 10.6 but without the time or expense of upgrading Filemaker Server.

I'm aware that FMS9 itself will not run on 10.6 but I'm hoping that doesn't apply to the WPE
