Yes, that is what I had in mind, though I think "upload" is a reasonable term for it.

I think the first priority is to analyze what is likely to happen with us pushing for
any particular thing, and then we can decide what we want to push for. I think it
likely that we will have the ability to create a single expensive "upload" (for less
than $1B) well before advanced nanotech, and given the vast amounts of money to be
made from one this is what will happen. Then its a matter of filling market niches
and business competition that I think leads to domination of the upload economy by
the first few thousand, and perhaps the first few ten, uploads. By the time your
"evoloads" show up, the game is basically over.
