I know that the virtual links work in a way so that several can multiplexed
across one physical link, and the manual quite extensively describes how to
implement a multipoint connection using a C104.

However, which is not evidently well described is if the VCP (Virtual
Channel Processor) on a T9000 is capable of routing messages through
to another physical link autonomously (like a C104).

As it looks like so far, one would still have to run a buffering process
to route through a virtual link.

Let me sketch the situation:

Tp 1     Tp 2     Tp 3
/------\ /------\ /------\	Will the VCP on Tp 2 automatically forward
|Vc A  | |Vc A  | |      |	messages on Virtual Channel C from Tp 1 to
|Vc B  |-|Vc B  |-|      |	Tp 3?
|Vc C  | |      | |Vc C  |
\------/ \------/ \------/

Anyone care to enlighten the matter?

It isn't. The T9000 does not, itself, provide through routing of its 
data links; that is the job of the C104.
