Can this be done? I know that using marshalling you can send objects
between
processes and/or AppDomains but what about sending file descriptors? In
Unix
(sorry) you do it with a special setup socket call and let the OS kernel
do
it's black magic to "convert" the file descriptor to something the
receiving
process understands.

But under WinXP and .NET 2.0+ (we're using 3.0 actually) is there similar
"black magic"? All my Google searches have only lead me to Unix answers.
....

To use handle in other process, you must call windows native API
(DuplicateHandle):

Between appdomains same handle should work I guess, because it's hosted in
the same process. Not sure though, I've never tested it.
