All of the threads *have* to know that you want to do this, and have to
either poll a queue of "things to do" or actively wait on such a queue
(in the same way that the UI effectively waits on the message queue).

Right. That's basically a producer/consumer thread. See
http://www.pobox.com/~skeet/csharp/threads/deadlocks.shtml
half-way down the page. You'll need to pass an object which contains
all the information you need. In many ways, this would be like the
information stored for a custom threadpool work item - see
http://www.pobox.com/~skeet/csharp/miscutil
for the code to such a threadpool. (The threadpool itself might not be
useful to you, but the bit that takes the parameters and invokes the
method might. See MiscUtil.Threading.ThreadPoolWorkItem.)
