Just out of curiosity, why is CredentialCacheService within the syncer
namespace, but not this class?

I was using the example set by ProfileSyncServiceFactory. Good point though.
I've put the factory into namespace syncer.

+class CredentialCacheServiceFactory : public ProfileKeyedServiceFactory {
+ public:
+  static syncer::CredentialCacheService* GetForProfile(Profile* profile);
+
+  static CredentialCacheServiceFactory* GetInstance();
+
+ private:
+  friend struct DefaultSingletonTraits<CredentialCacheServiceFactory>;
+
+  CredentialCacheServiceFactory();
+
+  virtual ~CredentialCacheServiceFactory();
+
+  // ProfileKeyedServiceFactory implementation.
+  virtual ProfileKeyedService* BuildServiceInstanceFor(
+      Profile* profile) const OVERRIDE;
+};
