We have never defined any installation userids on any SE. The only users 
defined are the standard IBM supplied one. Are you saying, if we defined at 
least a few of our own, we could have multiple 'sysprogs' logged on 
simultaneously?

1. Yes and this is recommended way. Note: you may keep completely unrelated 
CECs in single IODF.
2. There are many ways to update IOCDS. One of them is to update IOCDS in CEC 
#1 when working on LPAR under CEC #2. However for this scenario you need to set 
up your "CEC plex" or rather "SE plex" (SE=Support element). First step is to 
connect internal networks. Internal network is the LAN between HMC and SE. 
Usually it is three node network: SE, Alternate SE and HMC. Recommended way is 
to connect all the SEs and HMCs in one LAN (excluding optional remote HMC). You 
need to change SE and HMC adresses and change HMC name. Defaults are the same 
causing conflict.
Next you have to add CPCs (objects) to HMCs - the best way is every HMC manage 
every CPC. BTW: It is also good idea to set up domain security now. Otherwise 
someone with illegal CPC (grin) or illegal HMC would be able to connect to your 
SE plex.

Note: everything I described can be done remotely, however that require proper 
planning and order of changes. A mistake could cause a trip to datacenter to 
fix it. And be sure you have valid userids and passwords on each SE and HMC.
