[Milsurplus] Tube storage?

Hue sent:
Another thing i think about is, these tubes ain't being made any more, and 
your
precious tubes will eventually crap out, even the new ones, because the 
glass is
not 100% impermeable. Possibly we will pass from the scene before all the 
tubes
will, but be assured, tubes will one day be only "look at" items for 
collectors. The
only exceptions i can see is some tubes still kept in manufacture for the 
tube
audio cultists, tubes such as 6L6 and a few others.

Group:

Has anyone considered storing their tubes in a high vacuum?  Hard vacuum is a lot easier to come by these days than it was historically, so that would be one way to preclude migration through the envelope.  Or is internal out gassing the real problem?
