The android-sync sync adapter claims to support upload only syncs:

<sync-adapter xmlns:android="http://schemas.android.com/apk/res/android"
  ...
  android:supportsUploading="true" />

What this means is that when content is written to any of our registered ContentProvider's, Android will schedule a sync for us (generally 30 seconds after the write).  We should try to honour that sync request, at least better than we do now.

Suggestion: On upload only sync:

* short circuit "complicated" sync stages: if meta/global and crypto/keys are missing/stale, or we've been node re-assigned, or whatever, bail out until we request a full sync.

* query each local content provider using guidsSince().

* fetch() each modified GUID from remote, and store/reconcile with local.

* fetch() each modified GUID from local and store to remote.

This is as close to upload only as we can get.  Lame reality: with this scheme, we'll re-download all the records we upload this way, since their modified time on the remote server will be strictly after the last full sync.
