What I expect to really take off, though, is things like managed IT you do from home for some manufacturing company somewhere--small groups embedded or servicing larger companies that can be hired and spun up more cheaply from elsewhere in the country.
Basically, everything that people said would happen (but didn't work out) with globalization in knowledge worker industry, I personally expect to actually happen and work out with "domestication" of it to include a large segment of remote workers. The business considerations are mostly the same, minus the cultural, governmental, and time zone barriers that prevented it from working.
