I think there's a solution to all those Windows users who can't get Apache and PHP up and running properly on their machine.
Aprelium Technologies created the Abyss webserver. It runs has the ability to run ASP.Net and PHP side by side. It's easy to set up on Linux, Mac, and of course Windows. It installs in a flash, and is easy to configure.
It uses PHPs CGI interface, so not so sure how it will fair on all apps, but for quick & dirty testing, it's really good.
Any thoughts?
