This is a suggestion to add a +MIRRORS listing to a Gopher+ information blo= ck=20 (retreived via 'selector\t!' from Gopher+ servers). It would look somethin= g=20 like this:

---- +MIRRORS:=20 selector1\thost1\tport1 selector2\thost2\tport2 selector3\thost3\tport3 ----

Basically, this is a listing of servers that mirror the associated file, wi= th=20 the fields being the selection string, the host, and the port number, all= =20 delimited by tabs.

To ensure the servers really are hosting the same file, I suggest a cryptog= raphic=20 hash and OpenPGP key sign information also be added:

---- +HASH:=20 Algorithm: SHA1 Encoding: hex Value: c3ed72ece98f23239aea57f5c2aef64a0227198b

+SIGN:=20 *** OpenPGP signature block ***=20=20 ----

For the hash, 'Algorithm' can be either SHA1 or MD5--more could be added=20 in the future. 'Encoding' can be hex or base64 (others?).

The OpenPGP signature block is in ASCII Armor format, covered in RFC2440.

Servers supporting +MIRRORS can choose to return either +HASH or +SIGN or b= oth. It=20 is highly recommended to return at least one of them.

Thoughts?
