Can I use JIRA Service Desk with multiple users belonging to multiple orgs?

[Russell Grocott]

We would like to use JIRA Service Desk as a replacement for Zendesk.

For this to get off first base, we would need to be able to have an unlimited number of end users belonging to many separate organisations. The tickets raised by users should be visible either to that user alone or optionally visible only to other users belonging to the same organisation. 

Is this type of functionality available in the current release?

If not, is it planned?

Unlimited users - yes, you can have an unlimited number of "customer" accounts.

Visibility is a bit more of a pain - you need some way to tell JIRA that customers belong to the same organisation, then you can get part way there.
