<p class="MsoNormal">So first off, I'll be the first on in line to promote using OpenWRT for the basis of appliances for this sort of thing.  I use it to overcome the 'joy' of VirtualBox's local networking and love what it can do in 64M RAM.  <o:p></o:p></p>

<p class="MsoNormal">However, what you are describing are services, yes, but I think to focus on the OpenWRT part of it is missing the point.  For example, Neutron has a VPNaaS already, but I agree it can also be built using OpenWRT and OpenVPN.  I don't think
 it is a stand-alone service though, using a combination of Heat/{ansible|chef|puppet|salt}/any other deployment/orchestration can get you there.  I have a shell script somewhere for doing exactly that on AWS from way back.<o:p></o:p></p>

<p class="MsoNormal">What I've always wanted was an image builder that would customize the packages pre-installed.  This would be especially useful for disposable ramdisk-only or JFFS images that really can't install additional packages.  Such a front-end to
 the SDK/imagebuilder sounds like about half of what you are talking about above.<o:p></o:p></p>

<p class="MsoNormal">Also, FWIW, a while back I packaged up a micro cloud-init replacement[0] in shell that turns out to be really useful.  It's based on something I couldn't find again to give proper attribution so if anyone knows who originated this I'd be
 grateful.<o:p></o:p></p>
