I didn't say that :)  I can also imagine something like
SOCKETSERVER=1:~/socket/1

with the possibility to list several of them.

where 1 is the protocol number.  Note that there is no mapping of protocol
names to numbers in glibc at that place in the code right now (IIRC), so you
don't really want to add that.

Sure, this is a useful feature.  As I said, you must be a bit careful in
implementing it to stay secure, but I would say have a go at it.
