Pretty far, in my opinion.  Indiana has no CDE in it, which means no 
dtlogin.  This decision was driven by IP encumbrances and licensing issues.

SRSS does not work with gdm on Solaris today, and the version of gdm 
currently shipped with Solaris (including Indiana) has robustness issues 
when attempting to support multiple displays (related to multi-threading 
and signal handling).  Unfortunately, the gdm community has chosen to 
completely rewrite gdm from scratch rather than focus on fixing this 
issue, and it seems that the community's interests do not place dynamic 
display management high on the priority list for the rewrite (although 
that may be changing).  So it's unclear how long it will be before we 
have a stable gdm that SRSS can use for large scale deployments.  Until 
a suitable Solaris gdm is on the horizon, it makes little sense for us 
to invest effort in making SRSS capable of using it.  We may know more 
about this in a month or so - we're meeting with one of the gdm 
maintainers in late May to discuss gdm/SRSS issues.

On the Nevada/SXDE front, Sun is committed to maintaining dtlogin until 
a suitable gdm replacement is available.  We're having lots of internal 
dialog about when and how we can fully de-commit CDE at the moment.  Sun 
Ray is only one of the dependencies here.
