This is a bit beyond our scope here, but one ideal source for randomness
is LavaRnd: http://www.lavarnd.org/
If you set that up and run trickle, it will stock /dev/random with some
true randomness. I'm not sure why they apparently didn't increase
"/dev/random's vague notion of the amount of entropy available" since
lavarnd can generate so much random data quickly. That should be fixed
as far as I can see.
Getting this working with UML, and in fact feeding multiple UMLs with
high quality random data, would be very useful.
Related to this would be multiplexing PKI smart cards and HSMs accross
multiple UMLs. I'm going to need this soon.
