The 4 Roles of the Modern MSP

Question

The times, they are a changin’. When I look at my roles as an MSP and integrator at the turn of the century the equation for success started with selling solutions. In the SMB space, this consisted of file servers, email systems, and application and database servers for application software like Customer Relationship Management (CRM), Accounting, and other Line of Business (LOB) software. The old model value chain was driven by products and implementation. For me, as it was for most integrators, selling the hardware and software was a big ticket deal in itself. Even for small deployments, this could run into six figure invoices with nice margins. And, of course, you get to replace it all in 3-4 years when it’s slow, failing and outdated. Then there was the implementation and ongoing maintenance. Not a bad equation....

Thank you for your previous responses.
Im talking only about the T=0 case.
That was my opinion to, that somehow the applet author must know in wich case the APDU command is, based on the first 4 header bytes.
Do you know how the reading from the serial line is performed? I'm talking about the SetIncomingandRecive method, and the ReciveByte method. Those methods return the number of bytes the Card reads from the card reader. In the SetIncomingandRecive specification "This method gets as many bytes as will fit without buffer overflow in the APDU buffer following the header. It gets all the incoming bytes if they fit."
But I'm thinking that maybe when the applet calls the SetIncomingAnd Recive method ( and we are in the case where we have lets say three times o bytes than the APDUbuffer size), maybe at that time, all the APDUBuffer is not filled with data, then the JCRE should wait more until all the buffer will be filled? This can be seen in the return result of the SetIncoming.. and ReciveBytes methods. I'm asking you since you have more experience, do those reading functions read almost as much as the APDUBuffer size, in one call of each of the functions? or they read less bytes, something like half a buffer size.
For GemExpress X211 PK tool kit, can I donwload some applications on it without having the Gemplus special software. I do have the JCardManager working.
Thank you very much!!
