Couldn't an application like SetChannelVar(channel, var=data..) be the
solution here? Like the Set application,
but with a channel name to set the var in. If you use this application you
will be aware with possible race conditions
and deal with them in your dialplan.
We currently have applications like ChannelRedirect that work similar to
this, and I guess this application could
be used in these situations also.
To give the child channel the name of the parent you would just set a
variable with _ or __ and then use it in
this application.

Just a thought..
