I do mine inhouse.... using both win2kadvserv and RH7.2.
The current forum is www.amberorder.com
and the development/buildout server is at cave.amberorder.com.
The linux box runs apache, windows runs IIS5.0.
Linux = 800 mhz PIII
Win32 = 400 mhz PII
Needless to say, Linux is way faster. They share the same database, and the average pagegen time is .41 on win32 vs .13 on Linux.
Anyway, for those who are interested in such things... <g>
