[Freeswitch-users] Feedback on Freeswitch for Windows?

Hello For single-host settings, getting customers to buy a separate server just to run Freeswitch is overkill, so I'm thinking about selling just the IVR application to run on Windows. Unless a PCI card is available, the FXO connection will be provided by Sangoma's USB device. I'd like some feedback on running Freeswitch on XP and Vista: Is it ready for production use? Does it require beefy hardware? Thank you for any hint.
