It doesn't seem to be working for me:
I've set `glimpse-home' as below:

(setq nnir-glimpse-home "/home/reader/.glimpse-n2m")

I hit the right server (from your suggestions) as below:

(setq nnir-mail-backend (car (nth 5 gnus-opened-servers)))
returns:
(nnml "n2m" (nnml-directory "/mnt/pack/n2m/") (nnml-active-file
"/mnt/pack/n2m/active"))

and finally resetting:

`nnir-glimpse-remove-prefix'
M-: (setq nnir-glimpse-remove-prefix "/mnt/pack/n2m")

And by jove, it all worked.

Just looking at what was returned when I evaled:
(setq nnir-mail-backend (car (nth 5 gnus-opened-servers)))

It appears that at least 2 of the pieces of information that nnir
needs, to search a different server, are in that return.

Seems that nnir could be made to snarf it up by prompting the user for
a server name, then scanning that list for a match, slurping up the
strip prefix and name as it goes.

All thats missing in that picture is  the proper glimpseindex
directory.

Maybe if nnir required the user to name the glimpse indexs after
server names it could find the right one by the information included in:
(nnml "n2m" (nnml-directory "/mnt/pack/n2m/") (nnml-active-file
"/mnt/pack/n2m/active"))

Or when prompting the user for server name.
Completion could be used against that list to help the user get the
name right.

Or possibly nnir could be made to manage the glimpseindexing part too,
and would retain the directory/server  names.

Prompt:  What server would you like to index today:    <n2m><RET>
<nnir scans the list of servers, finds the name and calls glimpse to
index those files>
Prompt: indexing n2m .glimpse_FILES written to ~/.glimpse-SERVERNAME
