Comment(by zooko):

 USSJoin is considering using Tahoe-LAFS as the bulk storage for his
 gargoyle (as in Snow Crash) rig. He wants to be able to use it in caching
 mode for when he is offline, so that his files which are in Tahoe-LAFS are
 retrievable when off-line (because at least {{{K}}} shares of each file
 are stored in the local Tahoe-LAFS server which is on his person).

 I think he is wrong to want this! I think that caching should be done
 outside of Tahoe-LAFS instead of inside of it, such as by not running a
 Tahoe-LAFS server on his on-person rig at all but instead having a local
 filesystem on there with explicitly-managed local copies of some of his
 files.

 However, the great thing about this ticket is that it enables people to do
 things with Tahoe-LAFS that I don't necessarily think are a good idea. :-)
 In particular, USSJoin could specify that each file which is uploaded has
 to have at least K shares going to the one storage server which runs on
 his local rig.
