First of all, wow, that looks very interesting and in fact very much
what I'm looking for. As I mentioned in the original message, the
things this solution lacks are not something blocking for me.
Regarding the approach to Guacamole, I know that it's preferable to
have guacamole extension (that provides the dynamic inventory)
developed rather than meddle with the internal database but I guess it
is a good start.

Yeah, that's not a problem at all for me, the reasoning is sensible.

Regarding this, I agree with Julia.
I think OpenInfra Live would benefit from a VDI/DaaS-oriented session.

Any "quickstart setting up" would be awesome to have at this stage. As
this is a Django app, I think I should be able to figure out the bits
and bolts to get it up and running in some shape but obviously it will
impede wider adoption.
On the note of adoption, if I find it usable, I can provide support
for it in Kolla  and help grow the project's adoption this way.
Also, since this is OpenStack-centric, maybe you could consider
migrating to OpenDev at some point to collaborate with interested
parties using a common system?
Just food for thought at the moment.
