+An interesting benefit of using URL keys for this is the recently added
+VURL keys in today's release, which work just like url keys, except a
+checksum gets calculated when the content is downloaded from the url.
+This allows `git-annex fsck` to verify the checksums, as well as letting
+the checksum be verified when transferring the content between repositories.
+(See `git-annex addurl --verifiable` documentation.)
+
+And a nice thing about using URL or VURL keys for this is that it allows
+for both fully reproducible computations and computations that generate
+equivilant but not identical files. The latter corresponds to `git-annex
+addurl --relaxed`.
+
+If you use a VURL key and give it a size, then the checksum is calculated
+on first download from your compute special remote, and subsequent
+downloads are required to have the same checksum. Without a size, it's
+relaxed and anything your compute special remote generates is treated as
+effectively the same key, so there can be several checksums that git-annex
+knows about, attached to the same VURL key.

+About worktree provisioning, couldn't you record the sha1 of the tree
+containing the files needed to generate the object, and then use 
+`git worktree` to make a temporary checkout of that tree? You could
+`git-annex get` whatever files are necessary within the temp worktree,
+which could result in recursive computations to get dependencies.
+
+I would be careful to avoid dependency cycles though..

+On trust, it seems to me that if someone chooses to enable a particular
+special remote, they are choosing to trust whatever kind of computations it
+supports.
+
+Eg a special remote could choose to always run a computation inside a
+particular container system and then if you trust that container system is
+secure, you can choose to use it.

+About request one, receive many, it would be possible for a special remote
+to run eg `git-annex reinject --guesskeys` to move additional generated
+object files into .git/annex/objects/.
+
+(Doesn't datalad do something like that when it download and unpacks a
+tarball that contains several annexed files besides the one it was running
+the download to get? Or perhaps it only stores the tarball in the annex and
+unpacks it several times?)
