Loadable Streams Modules

| I note that the 4.1 Streams programming manual specifically states (on
| p.139) that streams modules are not dynamically loadable. Before I waste
| too much time, can anyone comment on (a) why not (b) why does
| /usr/sys/sun/str_conf.c seem to allow for it. I can't off-hand see any
| reason why it shouldn't work. You may know better...

(a) It is not implemented in the "vd" driver.  The "vd" driver is used to
    bootstrap the "loadable" driver into the kernel in happy fashion.  It just
    does not have support for it at this time.

(b) Just because their is some mention on this in an include module does
    not mean that its actually there.  

Their is no technical reason why this cannot happen, I believe that its a
matter of allocating resources for the project.
