I am planning on using a module like xhelp helpdesk for internal employees to log help desk tickets.

Is there any way to have custoemrs view/manage/update tickets (other than creating a normal user named customer).

I am looking for different ways.

E.g.
Any specific functionality in the HelpDesk module for use by custoemrs?

Any seperate modules that are specific for customers that connect to xhelp and all the xHelp tickets (just different user interface)?

Any suggestions to allow ticket transparency between Helpdesk and Customer to improve effeciencies?

Please help.
