The .NET Framework is an implementation of a published spec. Yes, Microsoft wrote the spec. That doesn't matter, what's important is that they adhere to it closely.
Today, that may be true, but that is no gurantee that it will remain so. Micro$oft not only "wrote the spec", but can change it as they see fit, at any time. To those who have followed MS Word document file formats' history, the lesson in this should be obvious.

Mono is not written by Microsoft. Microsoft does not maintain or support Mono. Mono is FLOSS. How is this any different from anything else we run on these servers? The thing I take exception to here is the broken logic: Microsoft wrote the spec, Microsoft sux, therefore the spec sux
I know that MONO is not written by Micr$oft.
I think it is different that "anything else we run on these servers" in that nothing else *I* am aware of is completely dependent upon a proprietary specification that can be changed at the whim of a single company. I think you "took exception" to "broken logic" that you didn't understand.
My thoughts run more like this: Micro$*ft controls the specification, irrespective of whether Micr$*ft sucketh or not, or whether the spec sucketh or not, why invest resources in supporting a specification controlled by a single commercial entity with a history of anti-competitive practices and poor standards compliance.
In reply to:
Mono is a completely independent FLOSS project that's been embraced by Novell (translate that to SUSE Linux).... While Mono is independent, Microsoft and Novell have partnered to ensure cross-platform functionality.
Of course Mono is FLOSS project. That said, you are not likely engender feelings of comfort or trust by reminding folks of the whole patents issue and how Novell "partnered" with Micro$*ft in regards to SUSE Linux.

In the past it was a clear line between Windows and *nix, Microsoft and "everyone else" but that line is starting to blur.
I don't see that line blurring at all, in spite of Micro$*ft's attempts to "play in both camps"

I think from a business perspective, DH should consider support for Mono because with the coming of Silverlight there will be new developers looking for hosts that support it - and they aren't any more eager to host over expensive Windows systems than the rest of us here.
I'm sure that, as is often the case, users of Micro$*ft technologies would like to avoid as much of the Micro$*ft "tax" as possible, but I'd far rather see mod_perl installed and available on DreamHost than I would mod_mono (though I would enjoy playing with Mono!)
