I'll add a "me too" to this.
I understand the DH position about adding functionality based on demand but we've had the discussion before and nothing ever comes of it. This can be a "chicken and egg" circular argument. Sometimes supply drives demand. You won't get people saying they want something that you obviously do not or will not support.
I can't use Mono at DH so I have to run/purchase other servers with other vendors for Mono and Microsoft.NET. I can't have people hitting my domain for a .NET web service, I need to give them alternative URIs. I was going to proxy requests through DH with PHP but it's a major pain.
There are a few hosts offering support for Mono but no providers with the same profile as DH. I think it would be a good marketing move for DH to offer Mono support as well as an ongoing lure for new business to support the initiative.
There are only a few primary web stacks in common use in this world:
All arguments aside about which platforms are the most popular, these are the main options, and it seems silly for DH not to support all of them. Mono is not a product of "the evil empire", and even if it was, techo-religion and other biases shouldn't influence which platforms are supported for business.
So I'd welcome Mono / C# / ASP.NET support here at DH. I'd use it a lot. I'd recommend DH in Mono venues. And I'd recommend a Mono / DH platform solution to more clients and colleagues when the opportunity arises.
Thanks for the consideration.
