  I'm going to send this on to the vcl-dev list - I think you are more
likely to get an answer there.

Re: Computer Lab

[Gabriel Muñoz <ga...@gmail.com>]

Hi Andy, thanks for your time. The university where I work, has time
and distance mode and virtual laboratories is an undeveloped theme. We
are trying to improve our virtual labs.

In this process of improving virtual labs we encountered several areas of work.
A central theme is the virtual laboratory software simulation of a
real experience. Where 3 teams developing the classroom Scorm
simulations themselves, the toolkit for real experience too, study
guides, etc.

Another focus: is the virtual laboratory as "online computer lab"
where students can use an operating system that is controlled, virus
free, with legal software, with libraries (dll) for each project, with
the versions of software proposed by the teacher, etc. This is useful
because at the time of evaluation or follow students' work is
complicated because the teacher can not play the simulations by
differences in software used by the student. For this axis VCL think
the project could serve us. To give students remote access to lab
machines.
Students now come with a generic user name and a generic pass several
times we realized the need to change this but we think it is the most
important thing right now. First we meet the need and then optimize
it.
On your windows xp example you install Cygwin only because it is
written in machine instructions for preparing laboratory encotramos
the requirements of vcl, we know that linux is to install programs on
a Linux operating system, but we do not need it (we believed that it
needed VLCD). VCL may not be the project that we need, if so do you
know anyone who can prove?.
We have chosen to implement open source software as we can.

The last line is that the teacher and student share the same desk
(same screen) to when they have questions and communicate with
teachers via chat, phone, video conferencing. As student and teacher
can interact together on the same screen. For this axis todabia not
find a opensource project that fits. Do you know any?

Thank you very much, hope not to have boring, only to tell the reality
of here and use that we give to the project.

Gabriel.

Hola,
VCL currently supports Linux and Unix lab machines.  Adding support for 
Windows has been a desired feature for a long time.  Since you already 
have Cygwin sshd working on the machines it wouldn't take much to allow 
VCL to provision them.

A few questions...
How do users normally log in to these machines?
Are they part of an AD domain?
Was Cygwin installed individually, via a GPO, or something else?
Do you know of anything else that you'd want to be automatically 
configured on the machine other than opening up RDP when a user makes a 
reservation?
