When the subject of running downspouts inside walls came up here some

leaking inside walls and such.

I think Tom is assuming that sewer-grade plumbing would be used, not
typical downspout crap. With how easy it is to assemble and glue PVC
or ABS, this is a very reasonabe assumption.

Well, now that you mention it, it does seem OK to do that--after all,
other waste pipes go inside walls, so why not storm drains?

Maybe the real problem is the outside connection with the gutter system,
although I suppose it should be possible to connect that securely too.

It's done on commercial flat roofs, all the time. There are code
requirements to meet. Just punching a hole in a soffit or fascia, to run
leaders on the interior, is not a good idea for obvious reasons.
