Description of problem:
I'm on production and am able to create more than one namespace:
----
Nams-MacBook-Pro:.openshift nduong$ rhc domain create -n nduong -l nduong+mac
Password: 
OpenShift Express key found at /Users/nduong/.ssh/libra_id_rsa.  Reusing...
Checking ~/.ssh/config
Found rhcloud.com in ~/.ssh/config... No need to adjust
Creation successful

You may now create an application.

Nams-MacBook-Pro:.openshift nduong$ rhc domain create -n nduong2 -l nduong+mac
Password: 
OpenShift Express key found at /Users/nduong/.ssh/libra_id_rsa.  Reusing...
Checking ~/.ssh/config
Found rhcloud.com in ~/.ssh/config... No need to adjust
Creation successful

You may now create an application.

Problem is, none of the tools/UI take this business logic change into account - e.g., I can't switch from one to the other using the rhc client tools or Web UI (assuming same for Eclipse plugin)

I'm not able destroy a newly created namespace at this point either:
---
Nams-MacBook-Pro:.openshift nduong$ rhc domain destroy -n nduong2 -l nduong+mac
Password: 
Problem reported from server. Response code was 400.
