Loyalty - Real Time Points Calculation

Hi Gurus

We have a requirement to make available a Real Time Points Calculation via an integrated solution.

So...unlike the WEB UI Process, where you can create an Activity online and then click process, we need to provide some sort of function module/web service which will not only create the Activity but also Process it as well and return an updated point balance.

From the Enterprise Services WIKI, I can see some Loyalty Web Services which Create Activities, but from the documentation it would appear that that is all that they do, they do not Process the activity. (Is this correct?)

The Web Channel (WCEM) solution appears to offer a Real Time solution, but I've not be exposed to how this works.

Does anyone know if this is possible via Standard or Non Standard Mechanisms?

What needs to done to make this work?

Many Thanks in advance for your assistance.
