Set up a DD-WRT consumer router for use with OpenDNS by way of 
dns-o-matic and you'll see how.  Now replace OpenDNS and dns-o-matic 
with your own services.

How is an RFC quote and an example of a running standardized application 
using the feature a 'no?'  Please read 
https://en.wikipedia.org/wiki/SRV_record and see just how standardized 
it is.

How do you guarantee a clean sandbox?  In the cloud case, every VM 
rolled is as clean as the template that generated it, and gives you a 
known starting point.  And I use PostgreSQL as the example since I 
maintained those RPMs for five years, and I understand the need for a 
clean sandbox, having learned the hard way what can happen if you don't 
take the care to make your sandbox clean (this was pre-mach, and 
definitely pre-mock, and buildroots had to be carefully regulated since 
they weren't cleanly sandboxed by mock and kin).

OpenStack will do most of what I'm talking about already.

That last point is exactly what UPNP was supposed to solve.

Such a device as you want exists; see the GuruPlug Display and 
descendants.  They are definitely tinkering boxen, and they do have 
their issues (I have a GuruPlug Server Plus with the eSATA port and the 
infamous overheating problems) but they are available.
