I like the idea behind the Verifiable ID venture by Steven Brill (news, press release, website).  It is an echo of my Trusted E-mail Network (TEN) idea: workable alternative for the needy.  But I don't see why security has anything to do with the ID when the real problem is the long line.  Having the ID doesn't excuse you from being searched before boarding.  It also doesn't offer any value beyond what passport provides.  Also, international travellers will get only half of the questionable benefit.

It will be a lot simpler and more effective to just sell private line passes for a frequent travellers.  It works just like those privately-operated freeways.  Companies can partner with airports and transport authorities to install and operate private lines wherever there are long lines.  With private and voluntary membership, they can be much through without ACLU screaming at them.

Besides, wouldn't you pay a little extra to get frisked by a sexy bombshell carrying an Uzi?
