A context file defines a set, not a set difference.
You could get a context file for each:

           darcs show changes --context --repo A >A.context
    ssh fs darcs show changes --context --repo B >B.context

but I'm not sure how useful that would be.

You can do it with pull, but apparently not with push.

    darcs pull --complement --repo B A A'

For example, suppose that I have a repo "darcs+twb", and I'm pulling in
David's changes from "darcs+droundy".  I can create a blacklist repo
"darcs+droundy.off" which contains patches I *NEVER* want, e.g. the ones
that refer to Franchise (Setup.hs, not Setup.lhs):

    darcs get http://darcs.net/  darcs+twb
    darcs get ...                darcs+droundy
    darcs init --repo darcs+droundy.off
    darcs pull --repo darcs+droundy.off darcs+droundy \
      --match 'touch Setup\.hs' --allow-conflicts

Then pull in other patches

    darcs pull --complement --repo darcs+twb darcs+droundy darcs+droundy.off
