Alternative to spark for Fastpath?

We use spark exclusively for FastPath but users are asking for alternative clients – this is for the fastpath requests/agent/operators. Are there any alternatives available to us? I dont think SparkWeb can handle fastpath requests? Is there any mechanism or changes to openfire plug-ins. anything? We do not want to reinvent the wheel. We use fastpath in a lot of places and the client side deployments are very flexible – we have no issue making them very custom – but it is also nice to give our users options on the client they use and it feels we are forced to use spark. We are looking for something relatively turnkey please
