Re: [Trustedjava-support] TSS access on TPM

[Ronald T. <ron...@ia...>]

Hi Paolo,

Just use the SOAP bindings for your application. Then the TCS will mange 
the TPM and act as server to as many client threads as you need.

At least in theory. :-) - Feedback and experience reports on this 
mechanism are welcome.
