Tell Dr.H to try to start with a short term visiting position (visiting instructor/honorary fellow/etc.) at some "reasonably good" (whatever that means) university. These are much easier to get than regular faculty ones (In many cases all you need is to know somebody who has a grant and is interested in collaborating with you. Such positions do not go through the formal hiring process and can, in fact, be offered by any faculty member: all one would really need is the chairman's approval and some source of money (say, a grant or a startup supported by some small contribution from the department if teaching is also involved). I invited quite a few people this way myself). That won't bring Dr.H high salary or job security but it may give him some extra time in the academic setting. What he makes of that time depends entirely on him. Of course, some "exit strategy" is a must for the case it doesn't work out. I wouldn't advise taking too much risk in the current economic situation with unemployment rates hovering over 10%.

@Greg The advertised level of seniority is not really negotiable and that has nothing to do with the department politics, it is just a legal issue. What you can negotiate though is the early consideration for promotion.
