The classes are a mess. Here's how they should look:

    def queryd(self, query, initBindings=None, format='python'): 
    def countQuery(self, query, initBindings={}):
    def add(self, triples, ctx):              # changed to a list, not *args
    def contains(self, stmt):
    def label(self, subj, default=''):
    def value(self, subj, pred, default=None):
    def subgraphLength(self, ctx):
    def subgraphClear(self, ctx):
    def dumpAllStatements(self):
    def remove(self, triples, ctx):           # changed to a list, not *args
    def save(self, context):                  # for certain remote graphs

cache = None
cache = PredicateCache(timeout...) # expires according to the predicate
cache = SubjectCache() # invalidates everything about a subject whenever you write to it

target can be an in-process rdflib berkeleydb path too

graph = SyncGraph(protocol='sesame', target='http://...', cache)
graph = AsyncGraph(protocol='sesame', target='http://...', cache)

inside, each real method calls prep, request, and processResult
pieces, which are connected together differently in the case of the
deferred api.

  request(method, rootUrl, path, queryparams, headers, payload)
  # streaming support for restkit?

# cache api
class Cache(object):
    def __init__(self):
       #
    def get(self, methodName, *args):
       # return result or Miss 
    def set(self, result, methodName, *args):
       # None

todo:
- remove 'remote' prefix everywhere?
- not makeConnection, but SyncGraph and DeferredGraph?
