nuhi did resume working on nLite in 2013. The latest version is
1.4.9.3, which may be the last version now that Windows XP and 2003 have both reached End-of-Support.
nuhi has since moved on to NTLite for later versions of Windows. (
homepage,
support on MSFN)
The last discussion on RVMi revival was in October of 2013. Source is available for the latest released beta, v1.6.1b2.1. YumeYao was working on a newer version in 2009, and he shared his source with me. I lost that source when my machines were lost that year. And he has been inactive for a few years now,
his last post on RyanVM's forum was 2012/09/12.
There's not much point in further development of RVMi now that Windows XP and 2003 have reached End-of-Support.
