The GNU Hurd has a lot of [[advantages]], but there are challenges, too.
+Some of these are explained in the [[hurd/critique]].

Even though they're quite popular in the simpler embedded space, there is no
successful true multi-server [[microkernel]] system for general-purpose desktop
use yet. This is still an ongoing research effort. (TODO: add references.)
Likewise, resource scheduling in distributed operating system kernels is a
research topic. For example, read more about it on the relevant [[Open Issues

+page|open_issues/multiprocessing]]. Also, the [[microkernel/Viengoos]]
+research kernel project strives to explore these.
TODO: more to come. [[!tag open_issue_documentation]]

+*Viengoos* is a research kernel, designed and written by Neal Walfield.
+
+As of late 2009, the project is on hold, due to time constraints.
+
+Viengoos is not really meant to be a successor to [[Mach]]. It is highly
+experimental; some of the techniques it employs, in particular, those related
+to [[memory_management]] and [[IPC]], are unproven. These were motivated by
+[[shortcomings_in_Mach|hurd/critique]] as well as current operating systems. A
+research system is unlikely the best base for a product. A better approach is
+to view Viengoos as an experimental platform whose goal is to explore solutions
+to some of the [[issues_uncovered_by_the_Hurd|challenges]]. Knowledge gained
+can then be integrated into something like [[Mach]].
The source can be downloaded from the *viengoos.git* repository, cf.
