Register MOSS system to SLD

Hello Experts,

I'd like to know if there is some way I could register a MOSS system (defined as far as I know as a 3rd party system) as a technical system into the SLD?

As for now, any ABAP or J2EE system is registered automatically to the SLD during installation. What is the case regarding a MOSS system? can it be defined as a Data_Supplier to a SLD_Client?

Thanks,

Tomer
