No problem. My experience has been mostly with SNL, LANL, and ORNL. These labs are richly stocked with extremely bright people working on solving some very important problems.
Some of these problems have commercial applications, some are strictly of value to the government, and some are so far out there that no one's really sure where they'll end up (how again was ARPAnet supposed to be used for defense?).
Two different points:
The problem with commercializing government technology is that you need an entrepreneur to push it. The labs do make overtures to allow their well-paid and securely-employed scientists to leave the nest, but the scientists seldom want to stop being scientists, give up a comfortable and tenured six-figure income, to network and sell when if they wanted to network and sell they wouldn't have gone for the Ph.D. in the first place.
If I'm in a metro area where I can, without moving, find a job making a comfortable living doing what I like after my startup fails, I'm much more likely to take that plunge. In "company towns" like Los Alamos or Oak Ridge, there really isn't any chance of that.
This leaves a relay baton drop between scientists who don't sell and would-be entrepreneurs with nothing worth selling.
No problem, the labs can license their stuff out. Problem, the terms of these licenses usually carve out a pretty generous chunk for the lab that spawned the technology, and the implicit terms include delays and risk of expropriation.
The terms of the lab carveout are often pre-ordained, based on revenues instead of margins, and don't take into account whether or not a business model can support them (because it has to be fair and defensible, and how do you know ahead of time what's fair?).
This leaves a would-be licensor to choose between many worthy projects, and as you want to be close both to your inventor and possible funding sources, this creates a bias toward licensing big-city lab technologies like those found at ANL, LLNL, LBL, NREL, and SNL-Livermore.
