1. A method for establishing a communications pipe between at least one PSD (40) and at least one Remote Computer System (50) over a network (45) using at least one Client (10) as a host to said at least one PSD (40), said at least one Client (10) and said at least one Remote Computer System (50) being in functional communications using a packet-based communications protocol over said network (45), said method comprising the steps of:

  • a) generating or retrieving, in said at least one Remote Computer System (50), a request (200;

    500) to access said at least one PSD (40), said request (200;

    500) being in a high-level messaging format, b) converting, in said at least one Remote Computer System (50), said request (200;

    500) from said high-level messaging format to a PSD-formatted request message (220;

    520), c) encapsulating, in said at least one Remote Computer System (50), said PSD-formatted request message (220;

    520) with said packet-based communications protocol, thus producing an encapsulated PSD-formatted request message (210;

    530), d) transmitting (230, 240;

    535, 540) said encapsulated PSD-formatted request message (210;

    530), using said packet-based communications protocol, from said at least one Remote Computer System (50) to said at least one Client (10) via said network (45), e) extracting, in said at least one Client (10), said PSD-formatted request message (260, 270;

    560, 570) from said encapsulated PSD-formatted request message (250;

    550), f) transmitting said PSD-formatted request message (260, 270;

    560, 570) from said at least one Client (10) to said at least one PSD (40), g) processing, in said at least one PSD (40), said PSD-formatted request message (260, 270;

    560, 570), thus producing a PSD-formatted response message (360, 370;

    660, 670), h) transmitting said PSD-formatted response message (360, 370;

    660, 670) from said at least one PSD (40) to said at least one Client (10), i) encapsulating, in said at least one Client (10), said PSD-formatted response message (360, 370;

    660, 670) with said packet-based communications protocol, thus producing an encapsulated PSD-formatted response message (350;

    650), j) transmitting (330, 340;

    635;

    640) said encapsulated PSD-formatted response message (350;

    650), using said packet-based communications protocol, from said at least one Client (10) to said at least one Remote Computer System (50) via said network (45), k) extracting, in said at least one Remote Computer System (50), said PSD-formatted response message (320;

    630) from said encapsulated PSD-formatted response message (310;

    610), and l) converting, in said at least one Remote Computer System (10), said PSD-formatted response message (320;

    630) into a high-level response message (300;

    600), and m) processing said high-level response message in said at least one Remote Computer System (50).
