Is it crazy to propose that the kernel should offer multiple devsrv sources?
It seems to me that it might be a useful to isolate proesses from things
that have been posted in /srv's even if they run as the same user under,
without preventing the use of /srv altogether.

If something like this is possible, how?  If not, has there just not been
demand?  Or is there some active problem with the idea of multiple named
pipe namespaces on one kernel?

Thanks much.

they aren't named-pipe name spaces, but holders of arbitrary file descriptors,
which allows them to hold references to any open device, including network connections.
that means there's no problem in principle with having more than one.
one (incompatible) convention would be to make new ones and allow
an attach name such as #sxyz to refer to a particular instance, "xyz".
another variant, which is orthogonal, would allow directory structures
and track ownership.

named-pipe spaces are created by binding #| to a name, and each one is a new pipe.
