This has been talked about a few times on the list, and I get someone 
emailing me every couple of weeks. So, ill repost the original mailing

Not quite the same thing, but I get your point. !M has said they were 
working on a client that would support multiple keys.

As for the "workaround", here is something to get you started.

Save this as /usr/bin/startnx

---Begin File ---
#!/bin/bash
nx_dir=/usr/NX
share_dir=$nx_dir/share
clientkey=client.id_dsa.key
MINPARAMS=1
if [ $# -lt "$MINPARAMS" ]
then
   echo "Usage: startnx {session name}"
else
   if ! [ -f ${share_dir}/${clientkey}.${1} ]
   then
     echo "Session key ${share_dir}/${clientkey}.${1} doesn't exist."
   else
     cp -f ${share_dir}/${clientkey}.${1} ${share_dir}/${clientkey}
     ${nx_dir}/bin/nxclient -session ${1}
   fi
fi
---End File ---

Copy the key files for each session to their respective names. E.g.

nx1 -> /usr/NX/share/client.id_dsa.key.nx1
local -> /usr/NX/share/client.id_dsa.key.local

etc...

you will need to change the permissions to the key files:

chmod 666 /usr/NX/share/client.id_dsa.*

and make your script executable:

chmod 755 /usr/bin/startnx

Then invoke like this:

startnx nx1

NOTE: This should only be done when you are the only one on your client
system. If it is a shared system, then you keys will be visible to other
users.
