1. An imaging-job-specific method utilizing display structure associated with a selected, single-site imaging instrumentality for enabling spontaneous, single-site control, by the selected instrumentality, over the execution of each single imaging job, employing, selectively, combinably and collaboratively, and specifically at the single site of the selected instrumentality, and via the mentioned, associated display structure, features of the different-instrumentality, native, imaging-activities functionalities and related user-accessible controls which are made available by selected ones of all of a plurality of currently available, operatively connected, different imaging instrumentalities, including features of such functionalities and controls that are furnished collectively, and if desired only, by plural such instrumentalities which are other than the mentioned, single-site, selected instrumentality, and wherein (a) each instrumentality has a respective user interface associated with its respective functionalities and controls, (b) the user interfaces of all of the different operatively connected instrumentalities are unknown to one another, and (c) the selected single-site instrumentality may be any one of the different instrumentalities, said method, with respect to the execution of a given, single imaging job, comprising establishing, with respect to a chosen plurality of such operatively connected instrumentalities, an appropriate instrumentality-intercommunication capability, utilizing that established capability, enabling the suitable, combined presentation, on the display structure associated with the selected instrumentality, of an active, singular-combined, integrated user combinational interface which, in relation to each given, user-intended imaging job, provides, via that singular interface, user-chooseable, simultaneous selection access to the various, different, instrumentality-specific, native, imaging functionalities and control combinations drawn from the availability of all of such instrumentalities' imaging functionalities and controls as reflected in the respective instrumentalities' image-handling user interfaces, including drawn from the availability of the functionalities and controls associated with plural imaging instrumentalities which are only other than the selected instrumentality, such presentation enabling displaying of the mentioned, combinational, integrated, singular interface including the capability for displaying therein instrumentality functional information selectively both (a) in an instrumentality-non-specific, non-differentiated manner, and (b) in an instrumentality-specific, differentiated manner, and in response to interface designation-invocation by a user of such presented and combined, individual-instrumentality, native functionalities and controls, executing the intact entirety of a given imaging job in the context of collaboratively and cooperatively-combinedly and selectively utilizing, via appropriate, inter-instrumentality routing, all of the so-user-chosen and designated, different, native functionalities, whereby a single, given imaging job may be executed, for finished outputting by one of the plural instrumentalities, by the uses of plural, native functionalities and controls that are offered by different, individual imaging instrumentalities.
