I keep getting more and more jealous of the few developers out 
there who are getting paid to write software in D.

I write D all day at Economic Modeling Specialists 
(www.economicmodeling.com) and we're always interested in resumes 
from experienced developers who know or want to learn D.

I wonder how many companies are using the language in production 
right now.

Should we start a page "They're using D" somewhere ?

Since you're hiring D developers, you're welcome to post job announcements in the D.announce n.g. It would also be awesome if your company would do a brief writeup about their use of D and real world experience with it.

Ask them officially first. They might see it as a win-win situation, since when programmers realize they can get real jobs in interesting fields using D, they might actually write resumes to those companies one day.

Hah, that's the ideal. It's not like we have some system of punishing people who screw up, we just expect people to learn from their mistakes, something which is not true of everyone.

When interviewing I'm observant to how candidates respond to various suggestions for improving their code. Some put effort in assessing the value of the suggestion and incorporate it if they find it good, or discuss it if they don't. Some others just make it a point that they didn't make a mistake, do all they can to defend code as is, and generally are unwilling to change code (even if sometimes is severely broken). That's a red flag. Andrei

Most of our projects track fairly closely with the latest DMD release; our main projects are on 2.062 right now. We have some fairly substantial codebases, so there's generally a two to four week lag in adoption of the latest release. Each project is free to work with whatever version they want, so we find DVM pretty handy. Each of the last few DMD releases has broken our latest big project, so there's generally a day of grumbling while we figure out what needs to change, then we forget about it. Our developers can request whatever hardware/OS they want to work on, with most folks on Linux or OSX and a few using Windows 7. Most production code is built and run on Debian servers, so we pay attention to Linux tool support but not much else OS-specific.

We do some pretty heavy stuff, numerics-wise, though I'm not sure what scale you think in. We have a simulation of the entire US economy (down to county and ZIP code geography, highly detailed demographics, all NAICS (industry codes), all SOC (occupation codes)) that can be perturbed via our online tool and which has response times measured in seconds. It's written entirely in D though it leverages Intel MKL for the linear algebra. Our US data processes are being transitioned over to D, the final product of which produces 10+ billion final data points per quarter. The dataset is largely synthesized, so there are many intermediate points. We have a lot of custom D code for doing things like solving inconsistent hierarchical, many dimensional, highly-underdetermined systems. We find that incorporating as much knowledge at compile time as possible tends to give very good results on the performance front. In some places we use CTFE to generate x86 assembly to do tricksy things like avoiding branching. In general I'd say that D's performance has been just fine; anything that isn't fast enough is usually already done better by tried and true C libs. And D makes calling those easy; LAPACK functions pack type and size information into their names, we make it easy to call the appropriate version by simply creating a general function for each C "overload set" that's templated on the type and number of arguments and which uses a string mixin to generate a call to the appropriate version of the C function.

In our case it's really that individuals are expected to own a project; we don't have a lot of external deadlines or requirements, so we can't afford to have people who require pushing. It's great because you generally get to work on what you want and take the time to do it properly, but that freedom can only work if there's a corresponding discipline and self-motivation.
