Walter, don't sweat it. You are amongst the MOST responsive product owners 
out there. Take your time and respond accordingly, is my advice.

I actually like talking to my customers <g>. Too many companies and their
developers seem to think that their tech support staff's sole job is to
prevent the engineers from ever having to talk to the customers. Sigh. I
spend at least half my day responding to email and ng postings. It's not a
burden at all, quite the contrary, that's how I learn new stuff and get
motivated to work on the product.

Let me mention a thought I had yesterday. In order to use D in a 
real-life environment I believe it would be very useful for our programs 
to be able to interact with components in other languages. This would be 
"a small door entrance" for the language but a very useful one until the 
libraries and controls are coded in D. In commercial environments we 
have lots of purchased or (long-time-ago) compiled libraries that still 
need to be used (c++, c, vb, now even dotnet).
How hard is it to make D interact with COM components, for example?

Pretty easy really, fundamentally speaking. It's not yet trivial in
practise, but the fundamental stuff is in there, so it will be in the long
run

D can hook directly to anything that can support C interfacing.

No problem - D interfaces are actually COM vtables!

and windows stdcall.

two problems .... COM interfaces are an ordered set of methods
D interfaces are an ordered set of functions (name +sig [not sure if it
includes return types as a java sig does])
if you declare 2 interfaces which both have a function with the same name
and signature then both interfaces get that as their implementation. you
chose it either change the interface name
or cheat, create a copy of the interface with a different name but the same
super i/f and layout and use that instead, (see problem 2)
you have to manually write QueryInterface ... being lazy I'd prefer a nice
way to get this automated, but it requires a solution to problem 1 (C++ has
the scope op :: to solve such issues)
as currently you can return any i/f you like for a given IID there is no
compiler checking that you are doing the right thing.
COM Delphi is a little easier, but C/C++ is a lot harder, even with ATL.
